Here is the graph for one equation in a system of equations:
a. Write a second equation in slope-intercept form for the system so it has infinitely many solutions.
b. Write a second equation in slope-intercept form whose graph goes through (0, -1) so the system has no solutions.
c. Write a second equation in slope-intercept form whose graph goes through (0, 1) so the system has one solution at (3, 2).
