Question

graph the horizontal or vertical line y = 1 use the graphing tool to graph the line

Explanation:

Step1: Understand the equation

The equation $y = 1$ represents a horizontal line. For any value of $x$, the value of $y$ is always 1.

Step2: Plot points

We can choose some arbitrary $x$-values like $x=- 3,x = 0,x=3$. The corresponding points are $(-3,1),(0,1),(3,1)$.

Step3: Draw the line

Connect the points with a straight - line. This line is parallel to the $x$-axis and passes through the point $(0,1)$ on the $y$-axis.

Answer:

Draw a horizontal line passing through the point $(0,1)$ on the $y$-axis. For any $x$-value on the coordinate plane, the $y$-value of the points on this line is 1.
