Front

What is the y-intercept in a graph?

Back

The point on a graph where a function crosses the y-axis (Where X=0); represented as (0,y). It is the 'b' in slope-intercept form.

Front

What does the y-intercept (0, 32) mean in a rental car context?

Back

It means that the cost before renting the car is $32.

Front

In the context of a carnival game, what does the y-intercept represent?

Back

The number of prizes the carnival has before 0 games are played.

Front

Which company shows a greater rate of change: Water's Edge Rafts or Ryan's Rafts?

Back

Water's Edge Rafts.

Front

What is the slope of the line if the change in y is 1 and the change in x is 4?

Back

1/4.

Front

Define slope in the context of a graph.

Back

Slope is a measure of the steepness of a line, calculated as the change in y divided by the change in x.

Front

What does a positive slope indicate about a function?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a function?

Back

A negative slope indicates that as x increases, y decreases.

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the formula for slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.
