Respuesta :

We will determine the rate of charge as follows:

*We will use two points from the graph. We can see that the following points are in the line:

(5, 50) & (10, 60)

Now, we calculate the rate of charge using the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

That is:

[tex]m=\frac{60-50}{10-5}\Rightarrow m=2[/tex]

So, it charges at a rate of 2 percent per minute [Option A].
