Question

What are the intercepts of this equation?
-2x+2y=-8

Answer 1

for x-intercept put y = 0 in -2x+2y=-8
for y-intercept put x = 0 in -2x+2y=-8

Answer 2

Intercept with x-axis, just do y=0---->-2x=-8--->x=4
Intercept with y-axis, just do x=0----->2y=-8--->y=-4

Answer 3

just write the eq'n in the for of x/a+y/b=1, a will be your x intercept & b will be your y intercept

Answer 4

Yes you have to substitute 0 for whatever variable you are not trying to find. For example:
To find x: -2x+2(0)=-8 and solve for x
Do the same thing for Y, except substituting for the available x, this time (x=0)
