Answer: $0.75

Step-by-step explanation:

-We know that the line must also contain the point (0,0), as 0 pounds of potatoes would cost $0. Thus we can find the slope of the line and write an equation:

slope = Δy/Δx = (3-0)/(4-0) = 3/4

y = (3/4)x

(The y-int (aka b) is 0 since the line passes through (0,0))

Plugging in 1 yields $0.75

Answer:

  • $0.75 per pound

-------------------------------------------------------

Proportional relationship equation:

  • y = kx, where k-constant of proportionality

Given point (4, 3).

Use its coordinates to find the value of k:

  • 3 = 4k
  • k = 3/4
  • k = 0.75

This is representing the price of 1 pound of potatoes.
