Question

Which of the following are equations for the line shown below (-1,5) (3,2) y - 5 = -0.75(x + 1)
B. y - 3 = -0.75(x - 2)
C. y - 2 = -0.75(x - 3)
D. y - 5 = -0.75(x - 1)

Answer 1

K so we have 2 get the slope? Can u do that?

Answer 2

lol 0.75

Answer 3

i came up with b and c

Answer 4

lol yeah true, smart u saw they all had -0.75 so yes lol that has 2 be it :p ok

Answer 5

Ok let me check

Answer 6

am i right?

Answer 7

Ok so u got C right, but B isn't.

Answer 8

Don't we... I don't know, need to see the line? :/

Answer 9

When u used (3,2) it gave u C now trying using point-slope formula with the other point (-1,5)

Answer 10

oh yeah true lol @terenzreignz it's either A or C but we need the line :p

Answer 11

Never mind, just saw the two points... :3

Answer 12

lolXD

Answer 13

wait, so do we need a line @terenzreignz ?

Answer 14

so my 2nd one is d?

Answer 15

couldn't it be either A or C ?

Answer 16

Two points are enough to determine the equation of the line :)
And these seem to be the two points that determine it all right :D

Answer 17

one is +1

Answer 18

oh yeah, A or C... strange...

Answer 19

il go wit c and d

Answer 20

Last resort... show the line :)

Answer 21

k hey ghost, type the A or C into www.wolframalpha.com and it'll show u the line equation & see which ones looks like ur answer.

Answer 22

it was a and c -_- i got to go brb

Answer 23

Both? LOL at least it's not wrong :D
