Given:
The dotted boundary line passes through the points (-3,-8), (1,-2) and (9,10).
Above line is shaded.
To find:
The inequality for the given graph.
Solution:
Consider any two points on the line. Let the two points are (1,-2) and (9,10). So, the equation of the line is:
Multiply both sides by 2.
Above line is shaded and the boundary line is a dotted line. So, the sign of inequality must be >.
This inequality is not in the equations. So, multiply both sides by -1 and change the inequality sign.
Therefore, the correct option is D.
