Question

1. graph the following equation. y = 4

Explanation:

Step1: Identify line type

The equation $y=4$ is a horizontal line, meaning the $y$-value is 4 for all $x$-values.

Step2: Locate the y-intercept

Find the point $(0, 4)$ on the coordinate plane; this is where the line crosses the y-axis.

Step3: Draw the horizontal line

Draw a straight, horizontal line passing through $(0, 4)$, extending infinitely left and right, since all points on this line have $y=4$.

Answer:

A horizontal straight line passing through all points where the $y$-coordinate is 4, e.g., $(-2,4)$, $(0,4)$, $(3,4)$, across the provided coordinate grid.
