x1 y1. x2 y2
solve with given points using the formula:
y2-y1/x2-x1
=
0-(3)
-4-(-1). = -3/-3 = 1 (slope)
plug slope and one pair of points into (y=mx+b)
(0) = -4(1)+b
=-4+b
4=b
add everything together:

Answer:
-4
Step-by-step explanation:
Pick any two points, let's go with (-7, 21) and (-6, 17) to find slope:
slope m = (y₂ - y₁) / (x₂ - x₁)
= (17- 21) / (-6 - (-7))
= -4 / 1
m = -4
---Extra info---
y-intercept using anyone point, let's use (-5, 13) and slope above:
y = mx + b
13 = -4(-5) + b
13 = 20 + b
b = -7
Equation of line:
y = mx + b
y = -4x - 7
Check:
(-7, 21)
y = -4x - 7
21 = -4(-7) - 7
21 = 21
(-4, 9)
y = -4x - 7
9 = -4(-4) - 7
9 = 9

t divided by 2 is equal to 11
Plzz help me
Answer: 22
Step-by-step explanation:
What divided by 2 equals 11? In other words, you have an unknown number (X), and then if you divide that X by 2 you get 11. Then what is that X?
The equation to calculate what divided by 2 equals 11 is as follows:
X/2 = 11
Where X is the answer. When we solve the equation by multiplying each side by 2, you get get:
X = 22
Therefore, the answer to what divided by 2 equals 11 is 22.

Answer:
anything to the power of 0 is always going to be 1 so the problem isnt as hard as it seems. so 1 million to the power of 0 will still be 1. so instead of the problem being 10,324 to the power of 0 by 8,576 to the power of 0 its really 1 x 1.
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
If you have a number with the exponent 0, then you should know that the exponent 0 always means 1. So, 10,324^0 is 1 and 8,576^0 is also 1.
Now, you have 1 times 1.
1 times 1 = 1
So, the answer is 1.

A box of cereal states that there are 87 calories in a 3-4cup serving. What is the unit rate for calories per cup? How many calories are there in2 cups of the cereal?
Answer: for 2 cups, There are 232 Calories.
Step-by-step explanation:
Step 1
Let the calories in one cup be represented as C
Therefore
3/4 x C = 87 calories
C = 87 X 4 / 3 = 116
unit rate is 116 calories per cup.
Step 2- Solving the number of calories in 2 cups
1 cup serving = 116 calories
2 cups servings = 116 x 2= 232 calories

2•3=6 +2=8 8 squared is 8•8 which is 64. This problem is quite simple.
Answer:
X=3
Step-by-step explanation:
Step 1: Find the square root of 64
since there is an exponent of 2 around your paranthesis, you must get rid of that first, by finding the square root of the first part of the equation and 64. then you will have (2x+2)=8
Step 2: Subtract 2
next subtract 2 from both sides of the equation, and you will have 2x=6
Step 3: divide by 2
lastly, divide each side by 2. you will get x=3
In the diagram below, we have ST parallel to QR. angle P= 40 degrees, and angle Q= 35 degrees. Find the measure of angles STR in degrees.
Answer:
[tex]m\angle S = 35^\circ, \ m\angle T = 105^\circ,\ m\angle R = 105^\circ[/tex]
Step-by-step explanation:
Similar Triangles
Lines ST and QR are parallel. Thus, angles S and Q are congruent, and angles T and R are congruent.
Considering the triangle PQR, the sum of its internal angles must be 180°:
[tex]m\angle P + m\angle Q + m\angle R = 180^\circ[/tex]
Substituting the known values:
[tex]40^\circ + 35^\circ + m\angle R = 180^\circ[/tex]
Solving for R:
[tex]m\angle R = 180^\circ - 40^\circ - 35^\circ[/tex]
[tex]m\angle R = 105^\circ[/tex]
Angles S and Q are congruent, thus
[tex]m\angle S = 35^\circ[/tex]
Angles T and R are congruent, thus
[tex]m\angle T = 105^\circ[/tex]
Summarizing:
[tex]\mathbf{m\angle S = 35^\circ, \ m\angle T = 105^\circ,\ m\angle R = 105^\circ}[/tex]

Step-by-step explanation:
using the slope formula find the slope of the line through the points (0,0) and (3,9) use pencil and paper explain how you can use mental math to find the slope of the line
Answer:
The answer is 3
Step-by-step explanation:
The slope is the intensity of inclination thus the slope of the line that passes through points (0,0) and (3,9) is 3.
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
The slope of a line that passes through (x₁, y₁) and (x₂, y₂) is,
Slope = (y₂ - y₁)/(x₂ - x₁)
Since the given line is passing through (0,0) and (3,9).
Slope = (9 -0)/(3 - 0)
Slope = 3
Since the line is passing through the origin (0,0) so we can do it by mental math to divide y and x coordinate directly like 9/3 = 3.
Hence "The slope is the intensity of inclination thus the slope of the line that passes through points (0,0) and (3,9) is 3".
