  Apply concepts of slope and y-intercept to graphs, equations, and proportional relationships.
a. Explain why the slope (m) is the same between any two distinct points on a non-vertical line in the coordinate plane.
b. Derive the equation y=mx for a line through the origin and the equation y=mx+b for a line intercepting the vertical axis at b.
  
Analyze and solve systems of linear equations.
a. Graph systems of linear equations and recognize the approximation of their intersection as the solution to the system.
