Exercise 8 Page 269

Plot the points on the same coordinate plane as the graph of the linear inequality.

C

Practice makes perfect
To check which point is a solution to the linear inequality, let's plot the points on the same coordinate plane as the graph of the linear inequality.
graph of the linear inequality and points

The only point that lies within the shaded region is (-1,-1). This corresponds to option C. Note that, if the boundary line had been solid, (-1,1) would have been a solution. Dashed lines mean that the inequality was either less than (<) or greater than (>), the values cannot be equal to those represented by the boundary line.
