Explanation:
You want a graphical solution for the system of equations ...
Graph
The graph and solution are shown in the attachment. A graphing calculator is a nice bit of useful technology for this. The solution is ...
(x, y) = (3.4, -0.2)
The first line has x-intercept 3 and y-intercept 1.5.
The second line has y-intercept -7 and slope 2. It crosses the x-axis at x=3.5, so will cross the first line in the 4th quadrant.
