What is a system of equations?

Back

A set of two or more equations with the same variables that are solved together.

Front

How do you represent the sum of two variables in an equation?

Back

The sum of two variables x and y can be represented as x + y = constant.

Front

What does the difference of two variables represent in an equation?

Back

The difference of two variables x and y can be represented as x - y = constant.

Front

What is the rate of change in a linear function?

Back

The rate of change is the ratio of the change in the dependent variable to the change in the independent variable, often represented as slope (m).

Front

How do you write an inequality for a given condition?

Back

An inequality is written using symbols like <, >, ≤, or ≥ to show the relationship between two expressions.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) of a function.

Front

What is a solution to a system of inequalities?

Back

A solution is any ordered pair (x, y) that satisfies all inequalities in the system.

Front

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

Back

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

Front

What does it mean for a variable to be less than or equal to a number?

Back

It means the variable can take any value up to and including that number.

Front

What does it mean for a variable to be greater than or equal to a number?

Back

It means the variable can take any value starting from that number and above.
