What does the graph of a linear inequality represent?

Back

The graph of a linear inequality represents all the solutions (ordered pairs) that satisfy the inequality, typically shown as a shaded region on one side of a boundary line.

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

Back

To determine if a point is a solution, substitute the x and y values of the point into the inequality. If the inequality holds true, then the point is a solution.

What is the significance of the y-intercept in a linear inequality?

Back

The y-intercept is the point where the line crosses the y-axis, and it helps in graphing the inequality by providing a starting point.

How can you tell which side of the line to shade when graphing an inequality?

Back

You can test a point not on the line (commonly (0,0)) in the inequality. If the inequality is true, shade the side containing that point; if false, shade the opposite side.
