Solve Systems of Equations by Graphing

Graph to find the solution. y = 3x – 12 y = -2x + 3 Solution: (3, -3)

Steps Make sure each equation is in slope-intercept form: y = mx + b. Graph each equation on the same graph. The point where the lines intersect is the solution. If they don’t intersect then there’s no solution. Check your solution algebraically.

1. Graph to find the solution.
