Answer:
y= -1/4x - 6
Explanation:
slope: rise over run
find a clear point such as (-4, -5) and count how many to the right and how many down so that you get to the point where it crosses the y-axis (0, -6).
so it is 1 down, and 4 across, giving you slope of -1/4. It is negative because it is going downwards.
as for the +b, it is the y value where it crosses the y axis. (0, -6). so you get -6
