Question

Derick is on the high school basketball team. He notices that the more rebounds he has in a game, the more points he scores. He plots the data on the scatter plot below from his last 19 games. Then he fits a line to the data to see the relationship and make predictions.



Which of the following statements are valid representations of the meaning of the 4 in the equation of the line?

Answer 1

Valid Not Valid
A 4 is the predicted number of points if there are no rebounds.
B 4 is the slope of the prediction line.
C 4 is the y-intercept of the prediction line.
D 4 is the predicted increase in points with each additional rebound.

Answer 2

Here's the question that baffles you at times.
Think it through.

D 4 is the predicted increase in points with each additional rebound.

Answer 3

B is false
C is true

Answer 4

On my paper:

T
F
T
F

Answer 5

D is false because the rebound doing y=mx+b would be for
1 y=6
2 y=8
8-6=2 not 4

Very good.

Answer 8

yay! :D

Answer 9

im going to try to do the next one by myself I'll let you know :)

Answer 10

Note that the difference is 2 points.

2 is the slope of the regression line.

The slope controls the increase in points for each additional rebound.
