The equation of a line in the point-slope form that has a slope of 1/3 and passes through the point (6,-2) is [tex]y+2 =\frac{1}{3} (x-6 )[/tex].
What is point-slope form?A straight line is represented using its slope and a point on the line using point slope form. In other words, the point-slope form is used to determine the equation of a line whose slope is "m" and passes through the point ([tex]x_{1}, y_{1}[/tex]). The equation of a straight line can be expressed in various ways, Point slope shape is one of them. The point slope form's equation is as follows:[tex]y-y_{1} =m(x-x_{1} )[/tex]where (x, y) is a chance point on the line that should be treated as a variable when using the formula.A fixed point on the line is ([tex]x_{1}, y_{1}[/tex]).The slope of the line is m.Calculation
[tex]y-y_{1} =m(x-x_{1} )[/tex]
[tex]y-(-2) =\frac{1}{3} (x-6 )[/tex]
[tex]y+2 =\frac{1}{3} (x-6 )[/tex]
Therefore, the equation of a line in the point-slope form that has a slope of 1/3 and passes through the point(6, -2) is [tex]y+2 =\frac{1}{3} (x-6 )[/tex]

1 can go on saturday and 14 can go on sunday; some of them can go on both days. how many people can only go to the game on saturday? 6
Answer:
No solution
Step-by-step explanation:
The reason why I say this problem has no solution is due to the fact that it says only one person may go on Saturday yet some fraction of the people between the numbers 1 - 14 can go. We have no idea what this fraction is, leading to a paradox of multiple equations and guesses desperately trying to figure out the number. Thus, the problem has no solution.

Can anyone write the equation of the graph?
The absolute value function y = |x - 3| + 5 generates the representation set on Cartesian plane.
What equation is behind a given graph?
In this question we need to determine the equation behind a representation set on a Cartesian plane. After a quick inspection, we find that the representation shows an absolute value function of the form:
y = |x - a| + b
Where:
a - Horizontal translation factor.b - Vertical translation factor.Based on all the given facts, the primitive absolute value function (f'(x) = |x|) is translated horizontally 3 units in the +x direction and vertically 5 units in the +y direction. If we know that a = 3 and b = 5, then we find the absolute value function y = |x - 3| + 5, whose representation is shown below.
In a nutshell, the representation comes from the absolute value function y = |x - 3| + 5.

A local movie theater is showing a new movie this weekend. The theater sold 144 tickets. Adult
tickets cost $9.00 each and a child's ticket costs $6.00 each. The theater collected $1164.00 from these
ticket sales. How many adult tickets and how many children's tickets were sold? Only an algebraic
solution will be accepted.
Answer:
a=100, c=44
Step-by-step explanation:
# of adult tickets is represented by a
# of child tickets is represented by c
C+A=144
9a+6c=1164
system of equations is solved by solving 1 equation for 1 variable first.
c=144-a
plug in c in the second equation
9a+6(144-a)=1164
9a+864-6a=1164
combine like terms
3a=300
a=300/3
a=100
now we know a is 100 we can plug it into the original equation of c=a=144
c+100=144
c=144-100
c=44
How many times greater is 1.88 times 10^2 than then mass of 2.35 times 10^-1
1.88 × 10² greater than 2.35 × 10⁻¹ by 800 times which is found by using division.
The two numbers given are:
1.88 times 10²
= 1.88 × 10²
And
2.35 times 10⁻¹
= 2.35 × 10⁻¹
We need to find that how much time is 1.88 × 10² greater than 2.35 × 10⁻¹.
We will use division for the same.
So, we get that:
= 1.88 × 10² / 2.35 × 10⁻¹
Using the rules of exponents and simplify the expression, we get that:
= 0.8 × 10 ²⁺¹
= 0.8 × 10³
= 0.8 × 1000
= 800
Therefore, we get that, 1.88 × 10² greater than 2.35 × 10⁻¹ by 800 times which is found by using division.

By evaluating the linear equation we will see that:
A = -3
B = 4
And the correct line is the purple one.
How to get the values of A and B?We know that the points (0, A) and (B, 0) lie on the line 3x - 4y = 12
To find the value of A, we can replace the values of the point on the line, so we get:
3*0 - 4*A = 12
-4*A = 12
A = 12/-4 = -3
A = -3
To get the value of B we do the same thing.
3*B - 4*0 = 12
B = 12/3
B = 4
So the points are (0, -3) and (4, 0).

The probability that a young adult chosen at random will achieve an IQ between 85 and 160 is 0.8185.
The problem states that;
A typical IQ test result for individuals between the ages of 20 and 34 has a mean of 110 and a standard deviation of 25, and the values are regularly distributed.
To get the probability that a randomly selected young adult will score between 85 and 160 on this IQ test.
Let,
P(85 < x < 160) = P[ (85 - 110)/ 25) < (x - μ) / σ < (160 - 110) / 25) ]
= P(-1 < z < 2)
= P(z < 2) - P(z < -1)
= 0.9772 - 0.1587
= 0.8185
Therefore, the probability that a randomly selected young adult will score between 85 and 160 on this IQ test is 0.8185.

The formula for the correlation coefficient is:
r = ( n∑xy -(∑x)(∑y) ) / ( √(n∑x² - (∑x)²) .√(n∑y² - (∑y)²) )
From the table:
∑x = 6, ∑y = 4258, ∑x² = 14, ∑y² = 4545234 and ∑xy = 6164
n = 4 (number of data points)
Substituting the values into the formula will give:
r = ( 4×6164 -(6)(4258) ) / ( √(4×14 - (6)²) .√(4×4545234 - (4258²) )
r = 24656-25548 / √(20).√(50372)

The vertices of a parallelogram are given, according to which the area of the parallelogram will be equal to 58 units.
What is perimeter?The perimeter of a shape is its boundary's length, regarded as a whole. A form's circumference can be calculated by adding the lengths of all of its sides and edges. Utilizing linear length units like centimeters, millimeters, yards, and feet, it is determined.
The total of all a parallelogram's sides is its perimeter.
Firstly, solve for vertices AB:
AB = √(17- 1)² + (1 - 1)² = 16
Then,
BC = √(22 - 17)² + (13 - 1)² = 13
Then,
CD = √(6 - 22)² + (13 - 13)² = 16
Lastly,
