7-48.

Consider this system of equations: Homework Help ✎

*y*= 2*x*− 8*y*=Use your knowledge of

*y*=*mx*+*b*to graph the lines without tables.Use the graph to find the point of intersection.

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.
