How do you draw straight line graphs of the form y equals mx plus c?

y=mx+c

y=slope(x)+(y-intercept)

1. put it in this form
2. then you put on the y intercept
3. then you put in the slope
4. ex: c=3 m= 4/3
5. rise 4 right 3
6. you now have 2 points on a straight line
7. if you need more points, treat the slope like a fraction
