What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is less than, greater than, less than or equal to, or greater than or equal to the other.

Front

What does it mean to solve an inequality?

Back

To solve an inequality means to find all values of the variable that make the inequality true.

Front

What is the solution set of an inequality?

Back

The solution set of an inequality is the set of all values that satisfy the inequality.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over the run between two points on the line.

Front

How do you find the slope from an equation in slope-intercept form?

Back

In the slope-intercept form y = mx + b, 'm' represents the slope of the line.

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac, allowing you to multiply a single term by two or more terms inside a set of parentheses.

Front

What is the first step in solving the inequality -4(3m - 1) ≤ 2m - 24?

Back

The first step is to distribute -4 to both terms inside the parentheses: -12m + 4 ≤ 2m - 24.

Front

What does it mean to isolate the variable in an equation or inequality?

Back

Isolating the variable means rearranging the equation or inequality so that the variable is on one side and all other terms are on the other side.

Front

What is an equivalent equation?

Back

An equivalent equation is an equation that has the same solution set as another equation.

Front

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

Back

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