The answer is B because the y intercept is where the line crosses the y axis and the slope is what I call rise over run which is where you see how many places each point is from each other in this case it is negative 6 and the divided by how many you go over which in this case is 2 so you get -3 and the y intercept would be -5 so the equation would be y=-3x-5.
