Extracted text: 1. For both parts a and b you will be working with the system of equations: [3x+7y=17 [2x– 21y=-117 a. Solve the system of equations algebraically. Remember to check your solution. Show all work in a clear, easy to read format. b. Solve the system of equations in part a graphically. Include a drawing of your graphs and label the solution. Your graphs should clearly show the horizontal and vertical intercepts of each line and the solution to the system of equations.
