Question

graph the following equation in a rectangular coordinate system.
y = -5

use the graphing tool to graph the line.

Explanation:

Step1: Identify line type

The equation $y=-5$ is a horizontal line, meaning the $y$-value is constant for all $x$-values.

Step2: Locate key points

Choose any two $x$-values, e.g., $x=0$ and $x=5$. The corresponding points are $(0, -5)$ and $(5, -5)$.

Step3: Plot and connect points

Mark the two points on the coordinate system, then draw a straight horizontal line passing through them, extending infinitely in both directions.

Answer:

A horizontal straight line passing through all points where the $y$-coordinate is $-5$, such as $(0, -5)$ and $(5, -5)$, extending across the entire rectangular coordinate system.
