Graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to x is 0.4. point, 1, point In other words, a change of 1 unit in x corresponds to a change of 0.4, point, 1 units in y. and a equation

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.

%40

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
