The graph shows the prices of different numbers of bushels of corn at a store in the current year. The table shows the prices of different numbers of bushels of corn at the same store in the previous year.

A graph shows Number of Bushels on x-axis and Price of Corn in dollars on y-axis. The x-axis scale is shown from 0 to 21 at increments of 3, and the y-axis scale is shown from 0 to 168 at increments of 24. A straight line joins the ordered pairs 3, 24 and 6, 48 and 9, 72 and 12, 96 and 15, 120 and 18, 144.

Part A: Describe in words how you can find the rate of change of a bushel of corn in the current year, and find the value. (5 points)
Part B: How many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? Show your work in words. (5 points)

A.  $8

B.  $1

Step-by-step explanation:

Part A:

Rate of change of any graph maybe interpreted by the gradient. In this case, since the line passes through origin, the gradient is:

The price this year is $8.

Part B:

Similarly, price in the previous year was

Change is $8 - $7 = $1  per bushel.

Part A:

The rate of change of the current year can be found taking the price of corn for that year and divide that by its respective number of bushels.

For example: It costs $48 to buy 6 bushels of corn, so 48/6=$8

So it's $8 per bushel for the current year

Part B:

The price of a bushel of corn is $1 more than in the previous year. The rate of change for the previous year is $7 per bushel while in the current year it is $8 per bushel. Since 8-7=1, this confirms that it's true.

step-by-step explanation:

y=mx+b

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
