Use a graph to approximate the solution of each system, List the estimated solution.
4. Sy = 5x - 3
5. Sy = 4x - 3
6. Sy=-3x + 7
Ly=-3x + 4
ly = 8x - 5

linear equations? Explain.
8. Elena and Marcus jog after school each day. One
day, Elena and Marcus jogged a total of 15 miles.
Elena jogged 1 mile more than Marcus. Use a graph
to find the number of miles each person jogged.
