See the entire solution process below:

Explanation:

To find the y-intercept, set xx to 00 and solve for yy:

(-6 xx 0) + 8y = -36(6×0)+8y=36

0 + 8y = -360+8y=36

8y = -368y=36

(8y)/color(red)(8) = -36/color(red)(8)8y8=368

(color(red)(cancel(color(black)(8)))y)/cancel(color(red)(8)) = (4 xx -9)/color(red)(4 xx 2)

y = (color(red)(cancel(color(black)(4))) xx -9)/color(red)(color(black)(cancel(color(red)(4))) xx 2)

y = -9/2

The y-intercept is -9/2 or (0, -9/2)

To find the x-intercept, set y to 0 and solve for x:

-6x + (8 xx 0) = -36

-6x + 0 = -36

-6x = -36

(-6x)/color(red)(-6) = (-36)/color(red)(-6)

(color(red)(cancel(color(black)(-6)))x)/cancel(color(red)(-6)) = 6

x = 6

The x-intercept is 6 or (6, 0)
