Consider this scatter plot. i took a picture of the answers and stuff.

Part A

8

The slope is 8 because it is the number in front of the x in y = 8x+40, which is the regression line. The regression line is in the form y = mx+b with m as the slope, so m = 8.

Part B

40

The y intercept is 40. This is where the line crosses the y axis. Referring back to y = mx+b form again, we see that y = 8x+40 matches up with b = 40. This point is at the location (0,40).

Part C

64

Plug in x = 3 and we get

y = 8x+40

y = 8*3+40

y = 24+40

y = 64

We predict a score of 64 when you study for 3 hours

Part D

In the context of this situation, the y intercept 40 means that if you put in 0 hours of study time, then you expect or predict to get a score of 40 on the test. This is the starting point so to speak because you can't put in negative hours to study.

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )
