To determine

To complete:

The givenstatement.

Answer to Problem 1E

The complete statement would be: The vertical change between two points on a line is calledrise, and the horizontal change is called therun.

Explanation of Solution

Given:

An incomplete statement:The vertical change between two points on a line is called $\underset{\_}{?}$ , and the horizontal change is called the $\underset{\_}{?}$ .

Calculation:

We know that the vertical change between two points is difference between the y -coordinates of two points and is known as rise. The horizontal change between two points is difference between the x -coordinates of two points and is known as run.

Therefore, the correct words for our given blanks would be “rise” and “run” respectively.
