Answer is D. -3/10x + 35

Step by step

The list of possible answers is

A. y = 3x + 35. B. y = –10x + 35. C. 3/10x -35. D. -3/10x + 35

When finding slope of random sets of numbers, each one is a negative slope and each one is a fraction. When a scatter plot of points are graphed from the set of points it shows a negative slope that is similar in slope to (y=-3/10x + 35) as shown by the yellow line.
