Answer: y = -4/5x-4

Step-by-step explanation:

You start with 4x+5y=-20

Isolate y by moving 4x to the other side, now your problem should look like:

5y=-4x-20

To get y by itself, divide both sides by 5, (don't forget to divide -20 by 5 too)

y=-4/5x-4

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
