Problem-Solving and Data Analysis practice question

Answer: 3

Slope is the change in y divided by the change in x. The change in y is 32 - 14 = 18 and the change in x is 8 - 2 = 6, so the slope is 18 / 6 = 3.

Common wrong answers

If you answered 6

6 is the change in x on its own. It is the denominator of the slope, not the slope itself.

If you answered 18

18 is the change in y on its own. Slope compares that change with the change in x, so divide by 8 - 2 = 6.

If you answered 1/3

You divided the change in x by the change in y. Slope is rise over run — the y-change goes on top: 18 / 6 = 3.
