4-50.

A 4 quadrant coordinate plane with 2 lines graphed. Line 1 goes through the points (negative 2, comma 0) and (0, comma 2) and is labeled Y = X + 2. Line 2 goes through the points (0, comma negative 1) and (2, comma 3).The graph at right contains the lines for and .  

  1. Using the graph, what is the solution to this system?

    What is the point at which the two lines intersect?

  2. Solve the system algebraically to confirm your answer to part (a).

    Use the Equal Values method by setting the equations equal to each other.

    Did you get the same solutions for and as in part (a)?
