Question

Find the coordinates of x−intercept and of y−intercept of the line. y=−3x−9

Answer 1

(-3, 0), (0, -9)

Explanation:

x-intercept: Let y = 0 and find x: 0 = -3x - 9), or 3x = -9. Then x = -3, and the x-intercept is (-3, 0).

y-intercept. Let x = 0 and find y. y = -3(0) - 9 = -9. The y-intercept is (0, -9).
