Question

Find the x-intercept and y-intercept for 9x - 8y = -72 
x-intercept: (,)
y-intercept: (,)

Answer 1

To find the x-intercept, we set y = 0 and solve for x.
9x - 8y = -72
9x - 8(0) = -72
9x = -72
x = -72/9
x = -8
So the x-intercept is (-8, 0).

To find the y-intercept, we set x = 0 and solve for y.
9x - 8y = -72
9(0) - 8y = -72
-8y = -72
y = -72/-8
y = 9
So the y-intercept is (0, 9).
