Here’s a good write up on it:

I was actually planning on typing out how to do it, but the link that Marconius provided is really good and explains it way better than I can.

i was acutally wondering how to change slope intercept form into point slope form

Ah, here we go. Gotta scroll down a bit:

slope-intercept form is the point-slope form taken at the y-intercept, or the point (0, y1):

y - y1 = m(x - x1)

y - y1 = m(x - 0) x1 = 0 since that’s the y intercept location

y - y1 = mx multiply the parenthesis values to M

y = mx + y1 add y1 to both sides and you’ve converted it.
