A system of linear equations is shown on the graph. The equation of one of the lines is y =-1/2x+4. What is the equation of the other line in the system? Graph shows two lines plotted on a coordinate plane. The first line goes through (0, minus 1) on Y-axis and (2, 5). The second line goes through (0, 4) on Y-axis and (4, 2) in quadrant 1. Both the lines intersect at X-axis 1.5 and Y-axis 3.2.
