The cross section is 10 ft by 15 ft
Answer: Choice C
(4, 18)
=========================================
Explanation:
One point shown on the graph is (2,9)
If we double each x and y coordinate, then
We go from (2,9) to (4,18)
Plotting this point on the graph will be on the same line as the other points.
Or you could note that y/x = 9/2 = 18/4 = 4.5
The problem ask to calculate the slope of the line base on the diagram or table you give. To calculate the slope you must first know its formula and that is Rise/Run and also be Y/X so you must divide the Megabytes and the Minute and with that calculation the slope is 3.75 so the equation will be y=3.75x
