1. Solve the linear system by graphing (find the point of intersection). (8 marks) To get full marks, you must graph the linear system correctly. y=2x+1 y=x-2 Point of Intersection: ( " ) 10 9- -8- -7 -6- -5- 4- 3 3 2 1- 1 2 3 4 5 6 7 -1- 2 -3- --4- -10 -9 -8 -7 -6 -5 -4 -3-2-10 -6- 7 -8- -9- 5 6 O --5- -10+ 8 910x 1. Solve the following TWO linear systems by method of substitution. Show your work! (6 marks + 6 marks) a) y = 3x-4 x+y=8 b) y = -2x+3 4x-3y = 1 2. Solve the following TWO linear systems by method of elimination. Show your work!
