First, find the slope of the two points.
y2-y1/x2-x1
3+2/8-4
slope=5/3
Then use the point slope formula to create an equation
y-y1=m(x-x1)
y-3=5/3(x-8)
y-3=5/3x-40/3
y= 5/3x - 31/3
The equation of the line that passes through the points (4, -2) and (8, 3) is
y = (5/4)x - 7.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Points:
(4, -2) and (8, 3)
The equation of a line is y = mx + c.
m = (3 + 2)/(8 - 4)
m = 5/4
Now,
(4, -2) = (x, y)
-2 = 5/4 x 4 + c
-2 = 5 + c
c = -2 - 5
c = -7
Thus,
The equation of a line is y = (5/4)x - 7.

The table contains a hospital's probability distribution chart of the number of babies born per day for a week. Determine the missing probability in the distribution, and then answer this question: What percentage of time should a sufficient number of nurses be on duty to care for at least seven babies?
Answer: 62.5%
Step-by-step explanation:
The probability of more than seven babies being born on any given day is (0.4375 + 0.1875+0)= 0.625. So a sufficient number of nurses to be on duty to care for at least seven babies is needed 62.5% of the time.

How can a diagram show you that corresponding parts of two triangles are congruent without providing specific angle measures or side lengths?
By using congruency definitions, we can show that corresponding parts of two triangles are congruent.
What is Congruent Triangles?Congruent triangles have the same corresponding angle measures and side lengths.
Given two triangles,
We can show that corresponding parts of two triangles are congruent by showing both the triangles congruent, then by CPCT we'll get the corresponding parts of congruent triangles are congruent.
Hence, By using congruency definitions, we can show that corresponding parts of two triangles are congruent.

What is the slope between these two points? (2,6) ( 3, 9)
Answer:
Slope of line
[tex] \frac{y2 - y1}{x2 - x1} \\ \\ = \frac{9 - 6}{3 - 2} \\ \\ = 3[/tex]
The slope of line is 3.
1) through: (-2,4), slope = 0
how you do this??
Answer:
y = 4
Step-by-step explanation:
I assume you want to find the slope-intercept form of the given information.
We are given the slope and a point, so we can find the y-intercept.
y = 0x + b
4 = 0(-2) + b
4 = 0 + b
4 = b
Put everything we know/solved for back into the formula [ y = mx + b ]
y = 4

Identify the form of each equation. 7x + 5y = 8 is in (select) . y − 5 = 3 (x − 9) is in (select) . y = 7x + 9 is in (select) . 8x − 9y = −2 is in
Answer:
Let's define all the possible forms:
slope-intercept: y = a*x + b
point-slope: y - y1 = a*(x - x1) (where (x1, y1) is a point in the line)
standard form: a*x + b*y = c
then:
a) 7x + 5y = 8
This is in standard form.
b) y − 5 = 3*(x − 9)
This is in point slope form.
c) y = 7x + 9
This is in slope-intercept form.
d) 8x − 9y = −2
This is in standard form.
Use the Distributive Property to simplify each expression.

Pls Help! John wants to prove ABC = to DEF. He Knoes AB = DE and AC = DF. With Screenshot
Answer:
[tex] \angle A \cong \angle D [/tex]
Step-by-step explanation:
The Side-Angle-Side method cana only be used when information given shows that an included angle which is between two sides of a ∆, as well as the two sides of the ∆ are congruent to the included side and two sides of the other ∆.
Thus, since John already knows that [tex] \overline{AB} \cong \overline{DE} [/tex] and [tex] \overline{AC} \cong \overline{DF} [/tex], therefore, an additional information showing that the angle between [tex] \overline{AB} [/tex] and [tex] \overline{DE} [/tex] in ∆ABC is congruent to the angle between [tex] \overline{AC} [/tex] and [tex] \overline{DF} [/tex] in ∆DEF.
For John to prove that ∆ABC is congruent to ∆DEF using the Side-Angle-Side method, the additional information needed would be [tex] \angle A \cong \angle D [/tex].
See attachment for the diagram that has been drawn with the necessary information needed for John to prove that ∆ABC is congruent to ∆DEF.
