The solution(s) of a system of linear equations give points of intersection of specific lines or planes.
The solution(s) of a system of linear inequalities give areas of intersection wherein any specific pair of points or lines are solutions.

The slope is 2. Use the slope formula (Y2-Y1/X2-X1) to find it, or count the rise over run.
