Write an equation in slop-intercet form for the line through points (2,4) and (6,-2).

What I did was:

-2 - 4 -6 3

------ = ---- = ---

6 - 2 4 2

Then

y - 4 = -3/2(x-2)

y - 4 = -3/2x - 2

answer

y = -3/2x + 2

Is this right? :confused:

You are correct up to the line

y - 4 = (-3/2)(x-2)

The continuation should be like this

y -4 = -(3/2)x -2(-3/2)

y -4 = -(3/2)x +3

y = -(3/2)x +3 +4

y = -(3/2)x +7 ----answer.

----------------

If the answer were

y = -(3/2)x + 2,

would points (2,4) and (6,-2) be in that line? - July 3rd 2005, 06:20 PMHayabusa
thank you.
