Front

What does it mean if a point is located on the line of a graph of an inequality with a dashed line?

Back

It is NOT a solution to the inequality.

Front

How do you determine if a point is a solution to an inequality?

Back

Substitute the point's coordinates into the inequality and check if it holds true.

Front

What is the graphical representation of the inequality y ≤ 5x - 1?

Back

A solid line for y = 5x - 1, with the area below the line shaded.

Front

What is the graphical representation of the inequality y > 2x + 3?

Back

A dashed line for y = 2x + 3, with the area above the line shaded.
