Question

use point slope form to write an equation of the line with the given slope that passes through the given point.

Answer 1

A. y - 0 = 2 ( x + 2 )

Explanation:

First you have to isolate y, by using A, the 0 can simply be forgotten about. Next, you must expand the equation, thus with 2 ( x + 2 ), it expands to:

y = 2x + 4

With this in mind, the b value is 4, and with a slope of 2, you can see that the equation eventually crosses the y-axis at 4.
