Question

What is the equation of the line that contains point (1, -2) and has a slope of 2?

O A. y = 2x - 5
OB. y = 2x - 4
O c. y = 2x+4
O D. y = 2x+5

Answer 1

B.
`y=2x-4`

Explanation:

The equation of the line with slope
`m` passing through
`(x_1, y_1)` is
`y-y_1=m(x-x_1)`.

`y+2=2(x-1) \\ \\ y+2=2x-2 \\ \\ y=2x-4`
