Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. For example, in the point (0,6), the y-intercept is 6.

Front

What does a greater rate of change indicate?

Back

A greater rate of change indicates that for each unit increase in x, the value of y increases more rapidly.

Front

What is the slope in the equation y=2x + 3?

Back

The slope is 2, which indicates that for every 1 unit increase in x, y increases by 2 units.

Front

Why is this function linear?

Back

This is a linear function because it has a constant rate of change.

Front

What is the slope represented in the table if it is 2?

Back

The slope of 2 means that for every 1 unit increase in x, y increases by 2 units.

Front

Define slope in mathematical terms.

Back

Front

What does a slope of 0 indicate?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant.

Front

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

Back

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form y = mx + b.
