The solution of a system of linear equations is (4,-2).
a. draw two lines that could represent this system of equations.
b. write the system you created.
c. solve your system using any method, besides graphing, to prove/check your system is correct.
y=-x+2 2y=x-8 these two lines both go through the point (4,-2) solve: substitute the y in the second equation with (-x+2): 2(-x+2)=x-8 -2x+4=x-8 add 2x on both sides: 4=3x-8 add 8 on both sides: 12=3x divide by 3 on both sides: x=4. find y: y=-x+2=-4+2=-2 the solution is (4,-2)
