Question

According to this site, if you know the coordinates of two points on a line, what form would you use to write the equation of the
line? Explain the process for writing the equation. (Site 1)

Answer 1

You would use the POINT SLOPE FORMULA and the Slope Formula

which is as follows ...

slope formula : $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

point slope formula:  $y - y_{1} = m(x - x_{1} )$
