Benchmark Review (Solving Systems of Equations)

Solve the system

• y=3x-6

• y=-x+2

• Solving means we want to find the x and y values that make both equations true.

• We can do this by graphing on our TI 84 calculator.

Solving using the calculator

• y= 3x - 6

• y= -x + 2

• Push y=, then put the top equation in y1 and bottom equation in y2

• hit graph, and your calculator will graph the equations

• push 2nd, trace, intersect, enter, enter, enter

• x=2 and y=0
