Answer 1

Well first you will need to find slope (m) by:\[\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]So choose one of the point to be (x1,y1) and the other to be (x2,y2).

Once you have found the slope then you'll be able to find the equation in point-slope form. So remember point slope form is\[y-y _{1}=m(x-x _{1})\] So any point for x1 and y1.

For Part 2: It doesn't matter what point you use because both points were used to find the slope.

Hope this helps and Good Luck :) If I made a mistake, sorry its been a long day.
