Question

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

Explanation:

Step1: Analyze the equation

The equation $x = 7$ represents a vertical line. In a rectangular - coordinate system, for every value of $y$, the $x$-coordinate is always 7.

Step2: Plot points

We can choose any values for $y$ such as $y=- 3,y = 0,y = 3$. The corresponding points will be $(7,-3),(7,0),(7,3)$.

Step3: Draw the line

Connect the points to form a vertical line passing through $x = 7$ on the $x$-axis.

Answer:

A vertical line passing through the point $(7,0)$ on the $x$-axis where for all real - values of $y$, $x = 7$.
