Question

graph the following equation in a rectangular coordinate system
x = 7
use the graphing tool to graph the line.

Explanation:

Step1: Analyze the equation

The equation $x = 7$ represents a vertical line. For any value of $y$, $x$ is always 7.

Step2: Identify points

We can choose some arbitrary $y$-values and the corresponding $x$-value will be 7. For example, when $y = 0$, the point is $(7,0)$; when $y = 2$, the point is $(7,2)$; when $y=- 2$, the point is $(7, - 2)$.

Step3: Plot the line

Plot these points on the rectangular - coordinate system and draw a straight vertical line passing through all of them.

Answer:

A vertical line passing through the point $(7,0)$ on the $x$-axis. All points on the line have an $x$-coordinate of 7 and can have any $y$-coordinate.
