Answer:
- solutions: (1, -2), (5, 2)
- not solutions: (-3, 6), (1, -7)
Explanation:
The first inequality describes a line with negative slope and y-intercept -4. The solution space is above that line.
The second inequality describes a line with positive slope and y-intercept +1. The solution space is below that line.
Together, the lines make a sort of X on the graph. The resulting solution space will be in the right-side quadrant of that X. Any sufficiently small y-value for a sufficiently large x-value will be a solution. Any point to the left of x=-4 will not be a solution. Values in each category are listed above and shown on the attached graph.
