Question

graph this equation: y = -2 click to select points on the graph.

Explanation:

Step1: Identify equation type

The equation $y = - 2$ is a horizontal - line equation where for all values of $x$, $y=-2$.

Step2: Select points

We can choose any values of $x$. Let's take $x=-3,x = 0,x = 3$. The corresponding points are $(-3,-2),(0,-2),(3,-2)$.

Step3: Plot points and draw line

Plot the points $(-3,-2),(0,-2),(3,-2)$ on the coordinate - plane and draw a straight horizontal line passing through these points.

Answer:

Plot the points $(-3,-2),(0,-2),(3,-2)$ (and any other points with $y = - 2$) and draw a horizontal line through them.
