Question

which of the following is the equation of the line passing through the points c(-1,1) and D(7,-1)

Answer 1

a. y+1=1/4(x-1)
b. y-1=-1/4(x+1)
c. y-1=4(x+1)
d. y-1=1/4(x+1)

Answer 2

is it just line passing or finding the slope to

Answer 3

just the line

Answer 4

okay, let me work on it

Answer 5

ok (:

Answer 6

use the formula of the line in two poin form
(y-y1)/(y1-y2)=(x-x1)/(x1-x2)
let any point be (x1,y1) so the other will become (x2,y2)
and by putting the values in the equation , you will get the equation of the line as
b)y-1=-1/4(x+1)

Answer 7

i did it and i did it in to different ways and got two different answers i got D y-1=1/4(x+1) and A y+1=1/4(x-1)

Answer 8

sorry if that doesn't help
