A graph plots Hours spent on homework, from 0 to 24, in increments of 2, versus Hours spent on video games, from 0 to 14, in increments of 2. Dozens of points fall diagonally in a relatively tight, narrow cluster between (0.5, 23.8) and (14.1, 3.1). A regression line falls diagonally through the center of the cluster from (0, 23) to (15, 3). All values estimated.

I think its D

Step-by-step explanation:

Answer 2

Answer:

Its A.

Step-by-step explanation:

The y-intercept of the model describes the average y value when x = 0.

In this case, x = 0 refers to students who spent 0 hours on video games.

The model indicates that students who spent 0 hours on video games will average 23 hours spent on homework.
