through: (-3, -1) and (2, 4)
Question 23 options:

A.) y + 1 = -(x + 3)

B.) y – 3 = x + 1

C.) y + 1 = x + 3

D.) y + 3 = x + 1

Answer 1

I thought it was B

Answer 2

\[y-y _{1}=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\left( x-x _{1} \right)\]

Answer 3

you are not correct.

Answer 4

it should start by y-(-1)i.e.,y+1 or y-4

Answer 5

How would you get the x part?

Answer 6

either x-(-3) i.e.,x+3 or x-2

Answer 7

then find the slope as given above.

Answer 8

So it's C?

Answer 9

it is a guess or calculated

Answer 10

anyway you are correct.
