When writing the name of a ray, the initial point is always written first. true or false?

A ray can be defined as :

A line with a start point but no end point (it goes to infinity) is called a ray.

The attachment shows a figure of ray.

When writing the name of this ray, we write it as

ray AB.

The non terminating point in written first and the terminating point is written after that.

So we can say its true that the initial point is written first.

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.

stops on an even number.
