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. It divides the coordinate plane into two regions: one that satisfies the inequality and one that does not.

What type of line is used for inequalities with < or >?

Back

A dashed or dotted line is used for inequalities with < or > to indicate that points on the line are not included in the solution set.

What type of line is used for inequalities with ≤ or ≥?

Back

A solid line is used for inequalities with ≤ or ≥ to indicate that points on the line are included in the solution set.

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

Back

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

What does the symbol '>' indicate in a linear inequality?

Back

The symbol '>' indicates that the values of y are greater than the values defined by the linear expression on the right side of the inequality.

What does the symbol '<' indicate in a linear inequality?

Back

The symbol '<' indicates that the values of y are less than the values defined by the linear expression on the right side of the inequality.

What is an ordered pair?

Back

An ordered pair is a pair of numbers (x, y) that represent a point in a two-dimensional space, where x is the horizontal coordinate and y is the vertical coordinate.
