Find the solution set of the system.
a. 
Alt text: A graph showing two solid lines that intersect at (0, 4) with a triangular shaped area
beneath that point shaded in. One line passes through points (-2, -4) and (2, 10) and the
other line passes through points (4, -6) and (-2, 8).
b. 
Alt text: A graph showing two straight dotted lines, one vertical and passing through the x-
axis at 3 and the other horizontal and passing through the y-axis at -4. The lines intersect at
point (3, -4). The area formed to the left of the vertical line and beneath the horizontal line is
shaded in.
c. 
Alt text: A graph showing two dotted lines that intersect at (0, 4) with a triangular shaped
area beneath that point shaded in. One line passes through points (-2, -4) and (2, 10) and the other line passes through points (4, -6) and (-2, 8).
