Question

graph the line y = - 7.

Explanation:

Step1: Identify line type

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

Step2: Plot points

We can choose any values of $x$, say $x=-3,0,3$. The corresponding points are $(-3, - 7),(0,-7),(3,-7)$.

Step3: Draw the line

Connect the points with a straight - line. This line is parallel to the $x$ - axis and passes through the point $(0,-7)$ on the $y$ - axis.

Answer:

Draw a horizontal line passing through the point $(0, - 7)$ on the $y$-axis. All points on this line have a $y$-coordinate of - 7 regardless of the $x$-coordinate.
