Answer: y = -x - 2

Explanation:

See attached for some more information on slope-intercept form.

We will create an equation with the given slope, plug the set of coordinate points in, and solve for our b variable.

y = -1x + b

-4 = -1(2) + b

-4 = -2 + b

-2 = b

This means the equation is;

y = -x - 2

We can also check our work by graphing. See attached.
