- Lines and Slopes Math -
**drwls**, Friday, January 7, 2011 at 7:20amHere are two hints:

(1) The first equation tells you that the slope of the line you are looking for is m = 3. That is because the line you want to be perpendicular to has a slope of -1/3.

(2) The y-intercept of the line you want is b = 20/5 = 4. The point is located at (0,4)

y = mx + b

Substitute in the m and b values from above.
