Convert to slope intercept form 4x+5y=-20

y = (-4/5)x - 4

slope = m = -4/5

y-intercept = -4

Step-by-step explanation:

slope-intercept form: y = mx + b

Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. Isolate the variable, y.

First, subtract 4x from both sides:

4x (-4x) + 5y = -20 (-4x)

5y = -20 - 4x

Next, divide 5 from both sides to isolate the y:

(5y)/5 = (-20 - 4x)/5

y = (-4x - 20)/5

y = (-4/5)x - 4

y = (-4/5)x - 4 is your answer.
