Question

9.9 line of fit how do you find the slope - intercept and how do u form an equation for these graphs?

Answer 1

equation: y=mx+b

m=slope

slope= rise/run

rise/run= y/x

b= y intercept

y intercept= wherever your slope meets a point on the y axis


so really...

y= change in y/change in x (x) + y intercept
