Help me people please

D. I think dear this is answer

C

Step-by-step explanation:

When the domain is y, the line is always horizontal

X could be anything and the line would still be horizontal because y is 1.5

Sorry, only have time to with the first with proportional relationships, you can simply divide the y coordinate by the x coordinate to find the unit rate: in this case, if (5,4) lies on the line then you have 5 lbs of potatoes for 4 dollars or .80 cents for 1lb of potatoes. the point (10,8) represents 10 lbs of potatoes for 8 dollars. here you can see that dividing 8 by 10 we once again get the unit rate of .80 cents per 1 lb of potatoes.. best of luck on the other two
