I feel really stupid that I can't find the equation of the following... is the y slope here 2?

I think so, ie. one unit across two up

Don't know what you mean "y slope." This plane appears to by generated by a line in the y-z plane whose slope (dz/dy) is -2. The equation of that line is z = -2y + 2. x is arbitrary.
