Explanation:
Two points on this line are (0,1) and (2,0)
Use the slope formula
m = (y2-y1)/(x2-x1)
m = (0-1)/(2-0)
m = -1/2
The negative slope means the line goes downhill as you move from left to right.
You didn't give us the choices. It doesn't matter. I think you're trying to write
Answer: 60 x² y⁸
The y has to be negative but the x positive. So that leaves only (3,-4)
