What is the slope of -12x-3y=21

-4

Step-by-step explanation:

-12x-3y=21

We need to solve the equation for y to get it in slope intercept form

Add 12x to each side

-12x+12x-3y=12x+21

-3y = 12x+21

Divide each side by -3

-3y/-3 = 12x/-3 +21/-3

y = -4x -7

This is in slope intercept form (y = mx+b  where m is the slope and b is the y intercept)

-4 is the slope and -7 is the y intercept

i know the answer is 3

no not all of them.

step-by-step explanation:

some of them have a square base.
