How do you graph the inequality y > x + 1?

Back

Graph the line y = x + 1 with a dashed line and shade the area above the line.

How do you graph the inequality y ≤ -x + 1?

Back

Graph the line y = -x + 1 with a solid line and shade the area below the line.

What is the difference between a solid line and a dashed line in graphing inequalities?

Back

A solid line indicates that points on the line are included in the solution (≥ or ≤), while a dashed line indicates that points on the line are not included (> or <).

What does it mean if a point is part of the solution set of an inequality?

Back

It means that the point satisfies the inequality when substituted into it.

How can you determine if a point is a solution to the inequality y < 2x + 3?

Back

Substitute the x and y values of the point into the inequality. If the inequality holds true, the point is a solution.
