The graph shows the number of public service announcements that a radio station played throughout the day. Public Service Announcements (PSAs) Aired

A graph has hours on the x-axis, and number of P S A's on the y-axis. A line goes through (1, 4) and (2, 8).

Which equation can be used to represent the number of public service announcements, y, in x hours?
y = StartFraction x Over 4 EndFraction
y = 4
y = 4 x
y = x + 4

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.
