Question

A proportional relationship between the number of pounds of cabbage (x) and the price in dollars (y) is graphed, and the ordered pair (5, 2) is on the graphed line.
Part A: What is the price of 1 pound of cabbage? Show your work. (8 points)

Part B: What does the ordered pair (10, 4) on the graph represent? Explain in words. (2 points

Answer 1

Answer:

see below

Step-by-step explanation:

Since it was a proportional relationship, it goes through point (0,0)

We have 2 points so we can find the slope

(0,0) and ( 5,2)

m = ( 2-0)/(5-0)

   = 2/5

The slope intercept form is

The slope is 2/5 and the y intercept is 0 since it goes through (0,0)

y = mx+b

y = 2/5 x +0

y = 2/5x

y = .4x

The price of 1 pound of cabbage is

y = .4 (1)

y = .40

$0.40  or 40 cents

(10,4)

This means that 10 pounds of cabbage is $4.00

Answer 2

Answer:

40 cents
