# How do you graph the line y=3?

Apr 19, 2018

I tried this:

#### Explanation:

In this case you can say that regardless of the $x$ value you choose the corresponding $y$ value will always be equal to $3$, so that you will get points with coordinates:

$\left(\text{any value} , 3\right)$

so when you plot these points you get a straight horizontal line that passes through $y = 3$ and is parallel to the $x$ axis:
graphically:

graph{0*x+3 [-10, 10, -5, 5]}
