can someone answer these 2 questions asap and thank you its also double the points because it 2 questions ;)

9:

r15.5 (not the one with the line under it i just couldnt find the one that didnt have the line under it)

for the graph, put 16 on the right side and label the lines right to left 16 15.5 14 14.5 etc. Put an open circle on the 15.5 line. then make an arrow pointing to the left.

10:

80p+64

This is because she needs 80 points OR MORE and (p represents the points) she already has 64. She needs 80 to be less than or equal to the amount of points earned.

The solution is 16p because 80-64=16 and p is needs to be greater than or equal to 16

answer: the equation matches the regression

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
