Question

Which of the following are point-slope equations of the line going through (6, 7) and (2, -1)? Check all that apply.

A. y - 7 = (x + 6)
B. y + 1 = 2(x - 2)
C. y + 1 = (x - 2)
D. y - 7 = 2(x - 6)
E. y - 7 = (x - 6)
F. y - 1 = 2(x + 2)

Answer 1

B

Answer 2

do you know the point slope equation ape?

Answer 3

No

Answer 4

do you remember the equation y=mx + b? pt slope is a variation of that,
y - y1= mx - x1 so then you just plug in the given x and y values

Answer 5

In this case the only one that works is (2,-1)
which becomes y - (-1)= m(x- 2)

Answer 6

which was the b option, they made it a little tricky by giving you an m value of 2
Do you see that?

Answer 7

i actually do

Answer 8

thanks!
