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:
[tex]Time[/tex]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:
[tex]Temperature\text{ }\mleft(\degree F\mright)[/tex]d) By looking at the graph, you can determine that the coordinates of point C are:
[tex]C\mleft(8,87\mright)[/tex]e) The x-coordinate of the point represents the time and the y-coordinate represents the temperature in °F. Then, since:
[tex]\begin{gathered} x=8 \\ y=87 \end{gathered}[/tex]You can conclude that the temperature on July 25th 2014 at 8:00 A.M. is:
[tex]87\text{ }\degree F[/tex]Hence, the answers are:
a) "Temperature on July 25th 2014".
b) Independent Variable:
[tex]Time[/tex]c) Dependent Variable:
[tex]Temperature\text{ }\mleft(\degree F\mright)[/tex]d) Coordinates of point C:
[tex]C\mleft(8,87\mright)[/tex]e) Meaning of point C:
The temperature on July 25th 2014 at 8:00 A.M. is:
[tex]87\text{ }\degree F[/tex]
