Question

Which of the following equations describes the line shown below? Check all that apply. (-3,4) (-1,1)



A. y + 1 = -(x + 1)
B. y - 4 = -(x + 3)
C. y - 3 = -(x + 4)
D. y - 4 = -(x + 3)
E. y - 1 = -(x - 1)
F. y + 1 = -(x + 1)

Answer 1

picture

Answer 2

the slope of the line is 1-4 / -1-(-3) = -3/2

Answer 3

which means?

Answer 4

hold on you got the points wrong aren't they (-3,4) and (-1-1)?

Answer 5

check out the diagram - the lower point is (-1,-1)

Answer 6

yes you are right

Answer 7

agreed?

Answer 8

agree

Answer 9

ok well that makes the slope (that is the gradient of the line)
= to difference of the y point / difference of the x points
= 4-(-1) / -3 - (-1) = 5 / -2 = -5/2

now the slope if the number whcih multiplies x in the equation of the line when we 'y'
so the equation is of the form y = -5/2 x followed by some number.

Answer 10

so I'm afraid it cannot be one of the eqautions you have listed.

Sorry apex - I cant help you any more - something is screwed up somewhere!

Answer 11

maybe we can pick the corresponding answers

Answer 12

none of the answers describes the line on the diagram - just as it was on your previous post

Answer 13

i can pick out any equations which fit the points - ok hold on

Answer 14

ok

Answer 15

right A and F fit (-1,-1)
B,D , E fit (-3,4)
C dont fit any

Answer 16

thanks

Answer 17

ok - yw
