Ответ:
-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
