Chapter 13: Q. 1 (page 525)

What is the x-coordinate of every point that lies on a vertical line through C?

Short Answer

Expert verified

The x-coordinate is 鈭�4.

Step by step solution

01

Step 1. Write the concept.

Horizontal lines go side to side and have a slope of 0. Vertical lines go up and down and have a slope that is undefined. Graph of horizontal lines are parallel to the x-axis. Graphs of vertical lines are parallel to the y-axis.

02

Step 2. Explanation.

The graph can be constructed as in below:

From the graph, the coordinate of the point C is (-4, 4).

03

Step 3. Conclusion.

If a vertical line passes through the point C, then the x-coordinate is (-4).
