Having taught his algebra students to solve linear-quadratic systems of equations graphically, Mr. Peters is preparing a lesson to show them how to use the table feature on a graphing calculator to generate the tables of values for given functions. First, the students will graph y = x² - 1 and generate the table of values. Then, the students will graph a particular linear equation in the same window and compare its table of values to that of the parabola. Mr. Peters wants to use a linear equation that will permit students to recognize that linear-quadratic systems can have more than one solution and to easily compare the graphical and tabular forms. Which of the following linear equations best supports his goals?

First, the students will graph y = x² - 1 and generate the table of values. Then, the students will graph a particular linear equation in the same
window and compare its table of values to that of the parabola.
Mr. Peters wants to use a linear equation that will permit students to recognize that linear-quadratic systems can have more than one solution and to
easily compare the graphical and tabular forms.
Which of the following linear equations best supports his goals?
A.y = 2x - 2
B.y = x - 2
c.y=-x-2
OD.y = -2x+2
