Front

What is the definition of Domain in mathematics?

Back

The set of all possible input values (x-values) for a function.

Front

What is the definition of Range in mathematics?

Back

The set of all possible output values (y-values) for a function.

Front

What are x-intercepts?

Back

The points where a graph intersects the x-axis (y=0).

Front

What are y-intercepts?

Back

The points where a graph intersects the y-axis (x=0).

Front

What is a linear equation?

Back

An equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

What does the slope (m) represent in a linear equation?

Back

The rate of change of y with respect to x; it indicates the steepness of the line.

Front

How do you write a system of equations?

Back

A set of two or more equations with the same variables.

Front

What is the purpose of solving a system of equations?

Back

To find the values of the variables that satisfy all equations in the system.

Front

What is the formula for calculating the total cost in a linear equation?

Back

y = mx + b, where m is the cost per item and b is the fixed cost.

Front

How do you determine the y-intercept from a linear equation?

Back

The y-intercept is the value of y when x = 0.
