Question

Sean drank a slushy as fast as he could.
The amount of slushy left in the cup (in milliliters) as a function of time (in seconds) is graphed.
How fast did Sean drink the slushy?
A. 10ml per second
B. 1 ml per second
C. 0.8 ml per second
D. 8 ml per second

Answer 1

d. 8 ml per second is the answer

Answer 2

Sean drank slushy  8 ml per second.

The correct answer is an option (D)

What is the slope of the line?

"The slope of the line passing through points $(x_1,y_1),(x_2,y_2)$ is,

$m=\frac{y_2-y_1}{x_2-x_1}$"

For given question,

From the graph, we can observe the line is passing through points         (0, 600) and (75, 0)

Let $(x_1,y_1)=(600,0),(x_2,y_2)=(75,0)$

The slope of the line would be,

$\Rightarrow m=\frac{y_2-y_1}{x_2-x_1}\\\\\Rightarrow m=\frac{0-600}{75-0}\\\\\Rightarrow m =\frac{-600}{75}\\\\ \Rightarrow m = -8$

This means, Sean drank slushy  8 ml per second.

The correct answer is an option (D)
