equal both sides to each other since they’re both equal to y. so -2x+2=-x-1
bring the x’s on one side and the numbers on the other by using opposite signs when bringing over.
-2x +x=-1-2 simplify. -x= -3 take out the negative by dividing by -1 on each side. x=3 now substitute ur x in ur equations with 3. so y=-2x+2 is y=-2(3)+2 which gives -4 and y=-x-1 is y=-(3)-1 which is y=3 then plot on graph
