Answer:
Answers are in bold in explanation
Step-by-step explanation:
We are given the equation:
y = -7x + 8
The first x value is 0
y = -7(0) + 8
y = 8
(0, 8)
The next x value is 7
y = -7(7) + 8
y = -41
(7, -41)
Now we are given the Y value instead of X, so we do this:
36 = -7x + 8
Subtract 8 on both sides to leave -7x alone
28 = -7x
Divide by -7 on both sides to isolate x
-4 = x
(-4, 36)
Answer:
(0,8) (7,-41) (-4,36)
Step-by-step explanation:
y = -7x + 8
y = -7(0) + 8
y = 8
(0,8)
y = -7(7) + 8
y = -49 + 8
y = -41
(7,-41)
(36) = -7x + 8
-7x = 28
x = -4
(-4,36)
