Math Practice Topic: Applied Linear Equations 2

Description: Creates word problems like these:
- What slope is perpendicular to slope 3/4?
- Based on equations, are the two lines parallel, perpendicular,or neither?
- Give the equation of the line that is perpendicular to y=x+3 and goes through point (3,4)
- Give the equation of the line that is parallel to y=x+3 and goes through point (3,4)

Adaptive Learning Progression: Covers perpendicular slopes by themselves, then applies this knowledge to equations.
