Answer:
-25
Step-by-step explanation:
You must first pick two points. I picked the points of (4, 400) and (8, 300). You can pick different points and still get the right answer.
Subtract the y's and the x's. Divide the difference of y by the difference of x.
400 - 300 = 100
4 - 8 = -4
100/-4 = -25
The slope, or rate of change, is -25.
Answer:
the value of x=
2×-12= -24
the value of y is 3y plus 20 which equals to 23
<h3><u>The x intercept is at (-7, 0).</u></h3><h3><u>The y intercept is at (0, 1).</u></h3>
To find both the x and the y intercept, we need to solve one at a time.
For the x intercept, we need to make the value of y equal to 0, and solve for x.
-x + 7y = 7
-x + 7(0) = 7
-x = 7
Multiply both sides by -1.
x = -7
The x intercept is -7.
Now for the y intercept.
-(0) + 7y = 7
7y = 7
Divide both sides by 1.
y = 1
The y intercept is at 0, 1.
