Question 1142614: please help me not just solve it but understand the following question because i don't have an instructor or anything like that, I am trying to learn this on my own. I have a text book but that only goes so far... Here it is:
Enter the equation of the following using line in slope-intercept form.
Two points on the line: (4, -2) and (-2, 4)

Slope-Intercept Form for a line, y=mx+b

m=%284-%28-2%29%29%2F%28-2-4%29, vertical change divided by horizontal change
m=6%2F%28-6%29
m=-1

Pick either of the given points of the line; if using (4, -2), then
y=mx%2Bb
y-mx=b
b=y-mx
-
b=-2-%28-1%29%284%29
b=-2%2B4
b=2

Equation for the line: highlight%28y=-x%2B2%29

The equation you're looking for is NOT highlight%28y=-x-6%29. 
So, IGNORE this equation: Equation for the line: cross%28highlight%28y=-x-6%29%29 from the other person.

At this site,  there is a group of lessons related to this class of problems
    - Find the slope of a straight line in a coordinate plane passing through two given points
    - Equation for a straight line having a given slope and passing through a given point
    - Solving problems related to the slope of a straight line
    - Equation for a straight line in a coordinate plane passing through two given points (*)
    - Equation for a straight line parallel to a given line and passing through a given point
    - Equation for a straight line perpendicular to a given line and passing through a given point

    - OVERVIEW of lessons related to the slope of a straight line

The most relevant to your current problem is the lesson marked  (*)  in the list.
So start from this lesson.

But if you want to learn the subject in all its aspects,  you need to learn all these lessons.

If you decide to do it,  then start from the very first lesson and go in that sequential order as shown in the list (!)

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