For y=mx+b is more like plugging in the numbers to help you draw a graph and identify points. For example, if you have the equation y=5x+8, you would use a graph to identify the points, you would use the rise over run method for this. Let's say a point is 2,18. x=2 and y=18. To check if this is correct you would solve the equation as shown. But the r also factors into this calculation. Therefore m = r*Sy/Sx. But we still have to find y intercept. We know for a fact that for the regression line function, we have Xmean and Ymean as part of its points or at its intersection. So we substitute the m, Xmean, Ymean, and then get Y intercept.It is important to ensure we do not confuse the two-intercept form of the equation of a straight line with the standard form 𝑎 𝑥 + 𝑏 𝑦 = 𝑐.
