What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols such as <, >, ≤, or ≥.

Front

What does the solution to an inequality represent?

Back

The solution to an inequality represents all the values that make the inequality true.

Front

How do you graph an inequality on a coordinate plane?

Back

To graph an inequality, first graph the corresponding equation as a line, then shade the region that satisfies the inequality.

Front

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows that one expression is greater than or less than another.

Front

What does the expression 3(x - 4) simplify to?

Back

3(x - 4) simplifies to 3x - 12.

Front

How do you solve the inequality 6 > x?

Back

To solve 6 > x, you can express it as x < 6, meaning x can be any number less than 6.

Front

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.

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x.

Front

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

Back

To determine if a point is a solution, substitute the coordinates of the point into the inequality and check if the statement is true.

Front

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, representing the value of y when x is 0.
