What's the slope of 4x+5y = - 20

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

-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
