Question

graph the horizontal or vertical line y = 2. use the graphing tool to graph the line. click to enlarge graph

Explanation:

Step1: Identify line type

The equation $y = 2$ represents a horizontal line. For any value of $x$, the $y$-coordinate is always 2.

Step2: Plot points

We can choose some arbitrary $x$-values like $x=- 3,-2,-1,0,1,2,3$. For each of these $x$-values, the $y$-value is 2. So the points are $(-3,2),(-2,2),(-1,2),(0,2),(1,2),(2,2),(3,2)$.

Step3: Draw the line

Connect these points to form a horizontal line passing through the $y -$axis at $y = 2$.

Answer:

Draw a horizontal line passing through the point $(0,2)$ on the $y$-axis. All points on this line have a $y$-coordinate of 2 regardless of the $x$-coordinate.
