Question

Which of the following is the equation of a line that passes through (-2, -1) and (-4, -3)?
A. y = x + 1
B. y = x + 1
C. y = x – 1
D. y = x – 1

i got D i just want to make sure this is correct?

Answer 1

It's not D, here's why

y = x - 1

-1 = -2 - 1 ... Plug in x = -2 and y = -1

-1 = -3

which is false

So (-2,-1) does NOT lie on the line y = x-1

Answer 2

btw, A and B are the same...and C and D are the same

Answer 3

i am so sorry i typed it in wrong
A. Y=1/2x+1
B.Y=x+1
C.Y=1/2x-1
D.Y=x-1

Answer 4

that's ok, but it's still not D for the same reason explained above

Answer 5

alright thank you for that explanation :)

Answer 6

np, what else did you get

Answer 7

i got the answer B

Answer 8

i did -1=-2+1
-1=-1

Answer 9

choice B is correct

Answer 10

but what about the (-4,-3)?

Answer 11

y = x + 1


-3 = -4 + 1


-3 = -3


which is true

Answer 12

so (-4,-3) lies on y = x+1

Answer 13

ohh it does go in! thank you sir for all the help :)

Answer 14

you're welcome
