Given two points, say points A and B, we can use the slope formula to find the slop of the line:

(y_(2) - y_(1))/(x_(2) - x_(1))

If A has coordinates of (w,c) and B has coordinates of (y,z), we can find the slope.

\frac{z-c[tex]y-w= (z-x)/(y-w) (x-c)}{y-w} [/tex]

Now we can say that we can use the point slope form formula:

y-y_(1)=m(x-x_(1))

Now we can substitute m for the slope, and use any points to plug in
x_(1) and
y_(1).

Hope this helps! :^)
