See the entire solution process below:

Explanation:

To find the x-intercept by substitution set y = 0y=0 and solve for xx:

2x - (3 xx 0) = -122x(3×0)=12

2x - 0 = -122x0=12

2x = -122x=12

(2x)/color(red)(2) = -12/color(red)(2)2x2=122

(color(red)(cancel(color(black)(2)))x)/cancel(color(red)(2)) = -6

x = -6 for y = 0 therefore the x-intercept is -6 or (-6, 0)

To find the y-intercept by substitution set x = 0 and solve for y:

(2 xx 0) - 3y = -12

0 - 3y = -12

-3y = -12

(-3y)/color(red)(-3) = (-12)/color(red)(-3)

(color(red)(cancel(color(black)(-3)))y)/cancel(color(red)(-3)) = 4

y = 4 for x = 0 therefore the y-intercept is 4 or (0, 4)
