Question

The following graph shows students’ test scores (S) in relation to the number of hours they studied (H). Which of the following is most likely to be the equation of the trend line for this set of data?


S = 6H + 45


S = 6H


S = 100 - 6H


H = 6S + 50

Answer 1

well it has to be \(S = f(H)\) right, so d is out, right? [you could r-write it so it's in terms of H but i think we can assume that it's out]

Answer 2

so of a) - c), which has a positive slope and an intercept that matches the graph?

Answer 3

would my answer be c?

Answer 4

what is the slope in c) ??
