Consider this system of equations: Homework Help ✎
y = 2x − 8
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.
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.
