Step-by-step explanation:
Answer:
x=0 and y=−8
Step-by-step explanation:
4x+4y=−32
4x−4y=32
Add these equations to eliminate y:
8x=0
Then solve 8x=0 for x:
8x=0
(Divide both sides by 8 to get x by itself)
x=0
Now we plug x back in to solve for y.
4x+4y=−32
Substitute 0 for x
(4)(0)+4y=−32
4y=−32 (Simplify both sides of the equation)
(Divide both sides by 4 to get y by itself)
y=−8
Y=mx+b
explaination- b is where the point starts. the + or - determines if the slope is positive or negative.
