How do you find an equation of a line with just two points?

OpenStudy (anonymous):

y-y1 = m(x-x1)

OpenStudy (anonymous):

x1 and y1 are the x and y values of one of the points

OpenStudy (anonymous):

and do (y2-y1)/(x2-x1) to get m

OpenStudy (anonymous):

in other words, the slope

OpenStudy (anonymous):

Okay. So can I do it with only one point (6,2)??

OpenStudy (anonymous):

well, no. you need the second point to get the slope

OpenStudy (anonymous):

y=mx+b

OpenStudy (anonymous):

Alright, thank you!!!

no problemo
