Answer:
Step-by-step explanation:
First we need to determine the equation of the boundary line.
The line has y-intercept of c=7 and slope .
The slope is given by y=mx+c.
We substitute the slope and intercept to get:
.
Since the lower half plane is shaded, with the boundary being a dashed line, the required inequality is
