Question 275881: Which of the following equations describes the line shown below? Check all that apply.
(4,6) (-1,-4)
A. y = 2x - 1
B. y - 4 = 2(x - 1)
C. y - 6 = 2(x - 4)
D. y = 2x - 2
E. y + 6 = 2(x + 4)
F. y + 4 = 2(x + 1) i tried this and the only one i got was b...but how do i know when its plus or minus on the equation???
Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!
Use the two point form of the equation of a line:
(x\ -\ x_1) )
where )
and )
are the coordinates of the given points.
Since which point you choose for #1 and which for #2 doesn't matter, you either get:
}{4\ -\ (-1)}\right)(x\ -\ 4) )
)
Which could also be written:
Or, if you swap the points:
\ =\ \left(\frac{(-4)\ -\ 6}{(-1)\ -\ 4}\right)(x\ -\ (-1)) )
 )
Which can also be written:
Looks like C, D, and F to me.
