Question

14. For the function rule y = -2x - 3, provide the x-y coordinates of the y-intercept and the x-intercept. Show your work.

Answer 1

For y-intercept, x = 0.
y = -2(0) - 3
y = 0 - 3
y = -3
y-intercept is (0, -3)

For x-intercept, y = 0.
0 = -2x - 3
2x = -3
x = -3/2
x-intercept is (-3/2, 0)
