solve both equations for y:

y >= -1.5x + 20

y <= -1.5x + 42.5

Same slope with different y-intercepts indicates parallel lines;

Graph both, which shows the solution set: solutions for 1st equation are above the line, and solutions for 2nd equation are below the line, which means no point(s) of commonality.
