Answer:
-4/5
Step-by-step explanation:
Lets put the equation in slope intercept form
4x+5y = -20
Subtract 4x from each side
4x-4x+5y = -4x-20
5y = -4x-20
Divide each side by 5
5y/5 = -4x/5 -20/5
y = -4/5 x -4
The equation is in the form y = mx+b where m is the slope and b is the y intercept
the slope is -4/5 and the y intercept is -4
