The rate of change of the X compared to the Y which is represented with m is the definition of the________ Slope
To make a graph given a Y-intercept and the slope, first you find the Y-intercepts, then use the slope to count ___________ and the _________ to find the next point. Rise, Run
In an equation in slope-intercept form you can find the Y-intercept: (where?) _______________________ Added or Subtracted to X
The slope-intercept form of an equation looks like; Y=___________________ mX + b
