Question

graph the line y = -2.

Explanation:

Step1: Identify line type

The equation $y = - 2$ represents a horizontal line.

Step2: Locate points

For any value of $x$, $y=-2$. So we can choose points like $(-3,-2)$, $(0,-2)$, $(3,-2)$.

Step3: Draw the line

Plot the points on the coordinate - plane and draw a straight line passing through them.

Answer:

Draw a horizontal line passing through the point $(0, - 2)$ on the $y$-axis. All points on this line have a $y$-coordinate of $-2$ regardless of the $x$-coordinate.
