When writing the equation of a line in slope‑intercept form, how can you determine the value of m in 𝘺=𝘮𝘹+b if you know the coordinates of two points on the line?

Answer 1

m = change in y coordinates divided by the corresponding change in x coordinates

slope = m = "rise over the run" = how much y changes for a given change in x

for example, if the two points are (2,4) and (5,7) the slope = (7-4)/(5-2) = 3/3 = 1
