See the entire solution process below:

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

$2x - (3 xx 0) = -12$

$2x - 0 = -12$

$2x = -12$

$(2x)/color(red)(2) = -12/color(red)(2)$

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

$x = -6$ 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 $(0, 4)$

How do you find the x and y intercepts of 2x-3y= -12 2x-3y= -12?
