y=mx+b form through points (h,k) and (p,v)

y-k=%28%28v-k%29%2F%28p-h%29%29%28x-h%29


y=%28%28v-k%29%2F%28p-h%29%29x-%28%28v-k%29%2F%28p-h%29%29h%2Bk
You can follow the method,...

Finding slope and picking the point for an equation (3,4)
m=%28%284-%28-2%29%29%2F%283-%28-1%29%29%29=6%2F3=2
y-4=2%28x-3%29

It is very elementary and basic skill that every student must develop to the level to solve such problems on his  (or her)
own without asking assistance from outside.


To help you to develop such skills,  the special lesson was created in this site
    - Equation for a straight line in a coordinate plane passing through two given points


Read it and then solve your problem.


From this lesson,  learn the subject once and for all.


=================

At the end of this lesson, you will find references (the links) to other lessons,
that cover the entire subject.

If you want to learn the entire subject, do not miss these lessons - - - look into them.


Then you will see sunrise (!)
