# Math Help - Simple Coordinate geometry...

1. ## Simple Coordinate geometry...

Because my mind is gone blank!....
If x = 1 how do I find what y equals?

I can't find it anywhere in my book!

2. I assume that we are talking about 2 dimensional Cartesian plane with x and y axes.

Now get a paper, draw the axes. And start plotting every point that has $x=1$. What does it look like?

3. Thank you so much! I think I get it now!
