iragen [17]

Answer:

The unit rate of $10 per hour.

Step-by-step explanation:

Given

x = time

y = amount

(x,y) = (1,10)

See attachment for graph

Required

What does the given point represents

From the attachment, the origin of the graph is:

(x_1,y_1) = (0,0)

and we have the given point to be:

(x_2,y_2) = (1,10)

Calculate the slope (m)

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{10-0}{1-0}

m = \frac{10}{1}

m = 10

The slope represents $10/1 hour

Hence:

(x,y) = (1,10) means the unit rate is $10 per hour
