Question

Use the graph below to answer the following questions:a) What is the title of the graph:b) Independent Variable:c) Dependent Variable:d) Coordinates of point C:e) Explain the meaning of point

Answer 1

Given the graph shown in the picture, you can identify that:

a) The title of the graph is: "Temperature on July 25th 2014".

b) The Independent variable is defined as the variable that does not depend on another variable.

An Independent variable is on the x-axis. In this case, you can identify that the x-axis of the graph represents Time. Then, you can determine that the Independent Variable is:

`time`

c) The Dependent variable is on the y-axis. Since, in this case, the y-axis represents the temperature in °F, you can determine that the Dependent Variable is:

`Temperature\text{ }\mleft(\degree F\mright)`

d) By looking at the graph, you can determine that the coordinates of point C are:

`C\mleft(8,87\mright)`

e) The x-coordinate of the point represents the time and the y-coordinate represents the temperature in °F. Then, since:

`\begin{gathered} x=8 \\ y=87 \end{gathered}`

You can conclude that the temperature on July 25th 2014 at 8:00 A.M. is:

`87\text{ }\degree F`

Hence, the answers are:

a) "Temperature on July 25th 2014".

b) Independent Variable:

`time`

c) Dependent Variable:

`Temperature\text{ }\mleft(\degree F\mright)`

d) Coordinates of point C:

`C\mleft(8,87\mright)`

e) Meaning of point C:

The temperature on July 25th 2014 at 8:00 A.M. is:

`87\text{ }\degree F`
