What is a linear function?

Back

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It is calculated as the rise over run.

Front

What is the y-intercept of a linear equation?

Back

Front

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

Back

To determine if a point (x, y) is a solution to a linear equation, substitute the x-value into the equation and see if the resulting y-value matches the y-value of the point.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution is the set of values that satisfy all equations in the system.

Front

What does it mean for a system of equations to be consistent?

Back

A consistent system of equations has at least one solution. It can be either one unique solution or infinitely many solutions.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input (x-value) is associated with exactly one output (y-value). A relation can have multiple outputs for a single input.

Front

What is the standard form of a linear equation?

Back

Front

How do you graph a linear equation?

Back

To graph a linear equation, find the y-intercept (b), plot it on the y-axis, use the slope (m) to find another point, and draw a straight line through the points.

Front

What is an inequality?

Back

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