MaryJo decided to solve the equation 3x-2= -x-6 by entering each of the expressions into her graphing calculator. To solve the equation as a system, she entered y1= 3x-2 and y2= -x-6. When she used the calculator to find the intersection, she found x= -1 and y= -5. Show the work to check to see if MaryJo found the correct solution for x to the linear equation.
