Front

What does the slope of a linear function represent?

Back

The slope of a linear function represents the rate of change of the function. It indicates how much the output value (y) changes for a unit change in the input value (x).

Front

What are fixed costs?

Back

Fixed costs are expenses that do not change with the level of goods or services produced by a business. Examples include rent, salaries, and insurance.

Front

What is the break-even point?

Back

The break-even point is the level of sales at which total revenue equals total costs, resulting in neither profit nor loss.

Front

How do you solve a system of inequalities graphically?

Back

To solve a system of inequalities graphically, graph each inequality on the same coordinate plane and identify the region where the solutions overlap.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate system, written in the form (x, y).

Front

What does it mean for a point to be a solution to an inequality?

Back

A point is a solution to an inequality if it satisfies the inequality when the coordinates are substituted into it.

Front

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

Back

To determine if a point is a solution to a linear equation, substitute the x and y values of the point into the equation. If the equation holds true, the point is a solution.
