Answer:
Work out the equations of the lines first.
The solid line
- It has a slope of m = (1 - 2)/2 = -1/2 and the y-intercept of 2
The line is:
The dotted line
- It has a slope of m = (-1 + 3) / 1 = 2/1 = 2 and the y-intercept of -3
The line is:
The intercession zone is above of both of the lines, so the inequalities are:
