Question

A line passes through (2, 8) and (4, 12). Which equation best represents the line?

1. y = 1/2x + 6

2. y = 2x + 7

3. y = 2x + 4

4. y = 1/2x + 10

Answer 1

I would say 3 (I am not completely positive, I am not that smart with graphs)

X: (2 + 4) / 2 Equals: 3
Y: (8 + 12) / 2 Equals: 10
Then multiple 3 by 2 get 6, add four, you get 10 which is equal to Y

Answer 2

y=2x+4 because we’re moving up 2 units for every unit we move to the right, and if we plug 0 in for X we end up with the +4
