Answer 2

What is the question?

Answer 3

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 for 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 14 at increments of 2, and the y-axis scale is shown from 0 to 98 at increments of 14. A straight line joins the ordered pairs 2, 14 and 4, 28 and 6, 42 and 8, 56 and 10, 70 and 12, 84.


Previous Year
Number of Bushels
Price of Corn (dollars)
2
10
4
20
6
30
8
40


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. (5 points)

Answer 4

it's extra credit work because i failed it :C

Answer 5

can u help a llama out?

Answer 6

@Dani_Rose

Answer 7

For part A all you need to do is find the slope

Answer 8

owe okay

Answer 9

can u help guide me i never been to great with graphs

Answer 10

To find the slope you don't need a graph. You are given coordinates that you can use.

Answer 11

i know what the equations suppose to look like y = mx + b

Answer 12

im just not sure what to do

Answer 13

sorry for my supidity

Answer 14

The formula for slope is \[\frac{ y_2-y_1 }{ x_2-x_1 }=slope\]

Answer 15

owe never knew that

Answer 16

Pick two of the point given to you and plug it into the equation

Answer 17

ok 2,10 and 4,20

Answer 18

Okay now we have (2,10) and (4,20)
Plug that into the equation to get\[\frac{ 20-10 }{ 4-2 }\]
Simplify to get\[\frac{ 10 }{ 2 }\]
2 goes into 10 exactly 5 times so the slope would be 5

Answer 19

thanks
