A. equation: y = -3x - 2

B. y-intercept: -2

Solution:

Given that,

Write the equation 12x = - 4y - 8 in slope-intercept form

The slope intercept form is given as:

$y = mx + c$

Where,

m is the slope and "c" is the y intercept

From given

$12x = -4y - 8\\\\Rewrite\\\\-4y-8 = 12x\\\\Move\ the\ constant\ to\ right\ side\\\\-4y = 12x + 8\\\\y = \frac{12x}{-4} + \frac{8}{-4}\\\\y = -3x -2$

Thus the slope intercept form is found

Comparing with y = mx + c ,

c = -2

Thus the y intercept is -2
