Question

Determine the intercepts of the line.

y=-3x + 12
y-intercept: (
a-intercept: (
0
,0
)
)
2-intercept:

Answer 1

x intercept: (4, 0)

y intercept: (0, 12)

Explanation:

The x intercept is whenever y equals 0, so if you plug in a 0 for y we need something to make the equation true. That would be a 4 for x because -3 times 4 is a -12, which plus 12 is 0. That makes the problem true for the x intercept. Now for the y intercept x is 0. -3 times 0 is 0, therefore we are left with 12. 12=12, so y would be 12. I hope this helps :)
