Find the x - and y - intercept of the line. x + 4y = 36

Plug in 0 for x to find the y-intercept

0 + 4y = 36

4y = 36

y = 9

y-intercept (0, 9)

Plug in 0 for y to find the x-intercept

x + 4 (0) = 36

x = 36

x-intercept (36, 0)

To find the x intercept, sub in 0 for y

x + 4y = 36

x + 4 (0) = 36

x + 0 = 36

x = 36 ... so x intercept is (36,0)

to find the y intercept, sub in 0 for x

x + 4y = 36

0 4y = 36

4y = 36

y = 36/4

y = 9 ... and y intercept is (0,9)
