I can't see pictures, so I'll do my best.
y= always stays the same.
To find the slope, or x, you have to start at the y-intercept, and find the number of units up, then right.
For example, y=4/3+6
4/3 is the slope because it goes up 4 units and right 3 units from the y-intercept.
6 is the y-intercept, which is the y-coordinate. It can also be graphed as (0,6).
