1 answer:

stiv31 [10]3 years ago

7 0

Answer:

Step-by-step explanation:

A.) As the number of hours spent on homework increases, the test scores received also most likely will increase.

B.) If someone does 2 hours of homework, you just sub in 2 for x, so you should get the equation y=8(2)+40, or a score of 56.

C.) The 40 is the y intercept, which means that the student is guaranteed to get at least a 40 on a test even if they study for 0 hours.

Hope this helps :)
