Question

graph the horizontal or vertical line. y = 7 use the graphing tool to graph the line.

Explanation:

Step1: Recall line - type rule

The equation $y = c$ (where $c$ is a constant) represents a horizontal line. Here $c = 7$.

Step2: Determine points on the line

For any value of $x$, the value of $y$ is 7. So, some points on the line are $(0,7)$, $(1,7)$, $(- 1,7)$ etc.

Step3: Plot the line

On a coordinate - plane, mark the points with $y$-coordinate equal to 7 and draw a straight line passing through them. This is a horizontal line parallel to the $x$-axis and 7 units above it.

Answer:

To graph the line $y = 7$, plot points such as $(0,7)$, $(1,7)$, $(-1,7)$ etc. and draw a horizontal line passing through them.
