find the slope, change in y (-1) divided by change in x (2) so slope is -1/2
point slope formula y-y1=m(x-x1) m slope and (x1, y1) point
y+2=(-1/2)(x+10)
y=(-1/2)x-7

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

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


At the end of this lesson, you will find the links to other lessons, covering the entire, more wide, subject.
Do not miss these lessons.

Consider them as your textbook,  handbook,  tutorials and  (free of charge)  home teacher.
