Question

What are the x and y-intercepts of the line described by the equation?
-6x + 3y = 18.9

Answer 1

x-intercept - x = 1/2y - 3.15

y-intercept - y = 2x + 6.3

Explanation:

For x,

-6x + 3y = 18.9

-6x = -3y + 18.9

x = -3y/-6 + 18.9/-6

x = 1/2y - 3.15

For y,

-6x + 3y = 18.9

3y = 6x + 18.9

y = 6x/3 + 18.9/3

y = 2x + 6.3
