Two ways to solve.

Plug-in the coordinate values and see which equation is true.

OR

Plug slope and given point into point-slope formula and simplify into general form.

they all have a slope of -2.
You need to see which equation has the point (4,-1) on it. Just substitute 4 for x and -1 for y in each equation. Then find the equation that ends up being a "true" result.
It's D since -1+=+%28%28-2%29%2A4%29+%2B7
-1+=+-8+%2B7
-1+=+-1 which is true
