What does it mean for a point to be in the solution set of an inequality?

Back

A point is in the solution set of an inequality if it satisfies the inequality when substituted into it.

What is the difference between a linear equation and a linear inequality?

Back

A linear equation represents a straight line and has an equal sign, while a linear inequality represents a region of the coordinate plane and uses inequality symbols (>, <, ≥, ≤).

How do you graph a linear inequality?

Back

To graph a linear inequality, first graph the corresponding linear equation as a dashed or solid line, then shade the region that satisfies the inequality.

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

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

Back

The y-intercept is the point where the line crosses the y-axis, indicating the value of y when x is 0.

Front

What does the term 'solution set' refer to?

Back

The solution set is the set of all values that satisfy a given equation or inequality.

Front

How can you determine if a point is a solution to a system of inequalities?

Back

Substitute the coordinates of the point into each inequality; if the point satisfies all inequalities, it is a solution.

Front

What is a system of inequalities?

Back

A system of inequalities is a set of two or more inequalities with the same variables.
