I just don't understand how to get the "slope" of a line xD

In that equation, y=2x-5, the formula y=mx+b, b is the y intercept. So, in this formula, the y intercept is -5. m is the slope. The slope is written as rise over run, and as you know, 2 can also be rewritten as 2/1, right? :D So the slope of the formula is 2/1. To get the slope, just count how many movements to the left/right, and up/down it is!
