9. Linear function f(x) = x is graphed on a grid. The graph of a new line is formed by changing the 5
slope of the original line to and the y-intercept to -8. Which of the following statements are true?
I. The graph of the new line is steeper than the original line.
II. The y-intercept has been translated down.
III. The new line and the driginal line are parallel.
a. I only
b. Il only
c. I and II
d. II and III

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
