It's a line.
This is a great tool for plotting things

If you wanted to plot the line yourself, pick an 'easy' value for x and then find the y that makes the equation true. I like to pick x=0.

So one point is (0, -2)
Now pick a second value. I like to pick y=0.

So another point is (4,0).
Plot those two points and draw the line that connects them.
Anytime the equation you are given has a single power of x added/subtracted to a single power of y being set to some number, you have a line.
