Module 12 Review

Front

What is a dependent variable?

Back

A dependent variable is the variable that is affected by the independent variable. In an equation, it is usually represented on the y-axis.

Front

What is an independent variable?

Back

An independent variable is the variable that is changed or controlled in an experiment to test its effects on the dependent variable. It is usually represented on the x-axis.

Write the equation for the cost of a taxi ride that charges a flat rate of $4.00 plus $0.95 per mile driven.

Front

What does the coordinate (0,1) represent?

Back

The coordinate (0,1) represents a point on the Cartesian plane where the x-value is 0 and the y-value is 1.

Front

What is the equation represented by the graph that shows a straight line passing through the origin with a slope of 2?

Back

Front

Define the term 'slope' in the context of a linear equation.

Back

The slope is a measure of the steepness of a line, calculated as the change in y divided by the change in x (rise over run).

Front

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

Front

What does it mean if a line has a positive slope?

Back

A line with a positive slope rises from left to right, indicating that as the x-value increases, the y-value also increases.

Front

What does it mean if a line has a negative slope?

Back

A line with a negative slope falls from left to right, indicating that as the x-value increases, the y-value decreases.

Front

What is the y-intercept of a linear equation?
