a) y = 0.004x - 4; the average number of posts per friend

b) y = -0.5x - 4; the amount of decrease in the gpa for each post

c) y = 0.05x - 4; the amount of increase in the gpa for each post

d) y = -0.004x + 4; the amount of decrease in the gpa for each post

the answer is D

y=-o.oo4x + 4; the amount of drcreases in the GPA for each post
