Chapter 13.1, Problem 2CE

To determine

To explain which of the following points lie on a horizontal line through C

Answer to Problem 2CE

The points are $\left(2,4\right),\left(0,4\right)\text{ and }\left(15,4\right)$

Explanation of Solution

Given information:

Looking at the graph in the given question

The point given is

  $\begin{array}{l}\left(2,4\right)\left(2,-4\right)\left(0,4\right)\\ \left(4,3\right)\left(15,4\right)\left(-4,3\right)\end{array}$

The y coordinate of point C is 4

Therefore,

Any other point with a y coordinate of 4 will be on the horizontal line through C

  $\left(2,4\right),\left(0,4\right)\text{ and }\left(15,4\right)$ points lies on a horizontal line through C

Hence,

The points are $\left(2,4\right),\left(0,4\right)\text{ and }\left(15,4\right)$
