help please! :)

Answer 1

A proportional relationship between the number of pounds of potatoes (x) and the price in dollars (y) is graphed, and the ordered pair (5, 4) is on the graphed line.

Part A: What is the price of 1 pound of potatoes? Show your work, including the proportion you used to determine the price. (8 points)
Part B: What does the ordered pair (10, 8) on the graph represent? Explain in words. (2 points)

Answer 3

I assume the relationship is linear in the form y = mx +c
If (5,4) is on the line we can calculate the equation
gradient m = change in y over change in x, = 4/5
y = 4/5 * x +c
4 = 4/5 * 5 +c
c = 0
y = 4/5 x
Part a if x = 1 then y = 4/5
part b is 2 times (5,4) so 10 pounds of potatoes cost 8 dollers

4/5=...?

Answer 13

0.8

Answer 14

ok!
1 pound of potatoes costs 0.8 dollars

Answer 15

finally, the ordered pair (10,8) represent the point which I get if I consider 10 pounds of potatoes, and which cost is 8 dollars.
Infact the costs of 1 pound of potatoes is 0.8 dollars, so the cost of 10 pounds of potatorùes is 0.8*10=8 dollars
