Question

A line segment is drawn from (3, 2) to (3, 9) on a coordinate grid.

Which answer explains one way that the length of this line segment can be determined?


A.Add 2 + 3.


B.Add 2 + 9.


C.Subtract 9 – 2.


D.Subtract 3 – 2.

Answer 1

C

Explanation:

Only C (subtract 2 from 9) could be true. This subtraction produces a measure of the vertical distance between the two points. (3, 9) is 7 units further above the x-axis than is (3, 2).

Answer 2

The answer is, C. Subtract 9 - 2
