• (7, 25)

• (3, 10)

The type of slope the line of best fit has is _______?

(positive, negative, or no)

For the graph shown, which two statements are a correct way to interpret the y-intercept?

• The calories started at 0.

• The initial time was 0 minutes.

• The initial calories were 0.

• The exercise log started with 0 minutes.

What is the slope of the graph shown?
Use the points (0,0) and (60,500) to determine the slope.

Check both the original AND reduced answer.

What is the y-intercept for the given scatter plot?

• (0,900)

• (900,0)

• 400/6

• -200/3

• 200/3

What does the slope mean in the situation shown?

• Mumps is not a disease you want to have.

• We have 400 more cases of mumps every 6 years.

• There are less cases of mumps as time goes on.

• There are 400 fewer cases of mumps every 6 years that pass.
