Answer:
The first graph is the solution to:
x = y - 2 (blue line)
y-8 = -1/2x (red line)
where the solution is (4,6)
The second graph is the solution to:
x = y - 2 (blue line)
y-8 = -2x (red line)
where the solution is (2,4)
Explanation:
The second equation is not clear. From the figures, the possible functions are: y-8 = -1/2x and y-8 = -2x.
To graphically solve a system you have to draw each line on the plane and look at the intersection point.
