Question

1. graph the following equation. y = -3

Explanation:

Step1: Identify line type

The equation $y=-3$ is a horizontal line (no $x$-term, so $y$ is constant for all $x$).

Step2: Locate the y-value

Find $y=-3$ on the vertical (y) axis of the coordinate grid.

Step3: Draw the line

Draw a straight horizontal line through this point, extending across the entire grid (it will pass through all points where the y-coordinate is $-3$, e.g., $(-4,-3)$, $(0,-3)$, $(5,-3)$).

Answer:

A horizontal straight line passing through the point $(0, -3)$ and extending infinitely left and right across the coordinate grid (all points on the line have a y-coordinate of $-3$).
