Interpreting Slope and Y-Intercepts

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

• (0,0)

• (10,100)

• (60,500)

• (100,0)

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 does the slope mean in the context of the situation graphed?

• You burn 500 calories every 60 minutes of exercise.

• You eat 500 calories when you eat out 60 times.

• You burn 100 calories every 10 minutes of exercise.

• You should not exercise.

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

• (0,900)

• (900,0)

• (2001, 400)

• (1995, 900)

Check the two ways you could write the slope for the graph shown.

Use (1995, 800) and (2001, 400) as two good points.

• -400/6

• 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.

Check two true statements about the y-intercept for this graph.

• The y-intercept is about (0,16).

• The y-intercept is about (16,0)

• The initial amount of reps for weight lifting is 16.

• The weigh lifting pounds begin at 140.

• The y-intercept 9s (140,0).

Check 2 true statements about the slope for this graph.

Use (0, 16) and (120,2) as "good points."

• You lose about 14 reps for every 120 pounds added.
  

• You gain 16 pounds for every 120 minutes of exercise.
