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.
