i think the correct answer is -8x+4
explanation:
This would be considered a rise over run. So you see where the line hits the point on the y intercept (thats where the four came from) and you count down until you see where the point hits on the x intercept ( thats where the negative 8 came from) and you go over one because thats where the point was, so you can write -8/1 or you can just do -8x.
