Tami keeps track of the number of trips she takes to the library and to the bookstore each month for a year. Her data is shown in the scatter plot below. Which equation could represent the line of best fit for the data in the scatter plot?

(d)

Step-by-step explanation:

answer cannot be (b) because the slope is negative

answer cannot be (c) because the slope steeper than -1/4

plugging points into a graphing calculator gives a line of best fit of:

y ~ 17/25x + 6

answer would then be (d)

step-by-step explanation:

first, eliminate the parenthesis:
