Question

What are the x and y-intercepts of the line described by the equation?
-3x + 9y = 18

Answer 1

The x intercept is (-6,0)

The y intercept is (0,2)

Explanation:

Let x = 0

-3x +9y = 18

9y = 18 Divide both sides by 9

y = 2

(0,2) This is the y intercept

Let y = 0

-3x = 18 Divide both sides by -3

x = -6

(-6,0) This is the x intercept
