7-48.
  1. Consider this system of equations: Homework Help ✎

    y = 2x − 8

    y = -2/3x

    1. Use your knowledge of y = mx + b to graph the lines without tables.

    2. Use the graph to find the point of intersection.

    3. Confirm this point of intersection by solving the system algebraically.

Remember:
b = the y-intercept
m = the slope

The point of intersection is (3, −2). Where is this point on the graph?

Use the Equal Values Method.
