Question

graph the linear equation y = 7. use the graphing tool to graph the linear equation. click to enlarge graph

Explanation:

Step1: Identify the equation type

The equation $y = 7$ is a horizontal - line equation where for all values of $x$, $y$ is equal to 7.

Step2: Plot points

We can choose any values of $x$. For example, when $x=- 3,y = 7$; when $x = 0,y = 7$; when $x=3,y = 7$. Plot the points $(-3,7),(0,7),(3,7)$ on the coordinate - plane.

Step3: Draw the line

Connect the plotted points with a straight line. This line will be parallel to the $x$ - axis and pass through the $y$ - value of 7.

Answer:

A horizontal line passing through the point $(0,7)$ (and all points where $y = 7$) on the coordinate - plane.
