x-intercept is x = 3/2x=32 or #(3/2, 0).

y-intercept is y = -3y=3 or (0, -3)

Explanation:

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

-6x + 3*0 = -96x+30=9

-6x + 0 = -96x+0=9

-6x = -96x=9

(-6x)/-6 = (-9)/-66x6=96

(cancel(-6)x)/cancel(-6) = 3/3 * (-3)/-2

x = 1 * 3/2

x = 3/2 or #(3/2, 0).

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

-6*0 + 3y = -9

0 + 3y = -9

3y = -9

(3y)/3 = (-9)/3

(cancel(3)y)/cancel(3) = -3

y = -3 or (0, -3)
