Answer:
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.
