Use format y = mx + b
-15x + 5y = 20
-15x + 15x + 5y = 20 + 15x
5y = 20 + 15x
y = (20 + 15x)/5
y = 4 + 3x
y = 3x + 4
m is the slope, so 3 is the answer
Use the slope-intercept form: y = mx + b
Fill in the things in: -15x + 5y = 20
Add into both sides "15x": -15x + 15x + 5y = 20 + 15x
Simplify the form: 5y = 20 + 15x
Add the x form into the area where it is supposed to be: y = (20 + 15x)/5
Simplify: y = 4 + 3x
Change around the two pieces: y = 3x + 4
3 is in the "m" area, also known as the slope, is the answer.
Hope this helped!
