Which is the equation to the line passing through points (2, –7) and (5, –1)

Question

raden · Answer

use the formula :
(y-y1)/(y2-y1) = (x-x1)/(x2-x1)

anonymous · Answer

use the formula @RadEn  gave you to find the slope of your line first.

anonymous · Answer

y = 2x – 8

y = – 2x + 9

y = 2x – 11

y = – 2x + 6

@Brittni0605  those are the answers i think its A

anonymous · Answer

No, its not A.

anonymous · Answer

then at @Brittni0605 what is it?

anonymous · Answer

anonymous · Answer

Understand?

anonymous · Answer

somewhat so does that mean that the answer would be c ?

anonymous · Answer

It means the answer could be A or C.

anonymous · Answer

But since I already told you its not A, you know its C.

anonymous · Answer

i asked u last time if it was A & you told me no its not

anonymous · Answer

thanks alot

anonymous · Answer

I said its not A. But based on just slope, your choices were narrowed down to A or C. To determine if it was A or C, you needed to find the b value in the equation y=mx+b
