The y value changes from y = 1 to y = 3, which is a change of 2 units. Call this P. So P = 2 = 2/1.

The x value changes from x = 3pi/2 to x = 2pi which a difference of pi/2. Call this Q. So Q = pi/2

Divide P over Q:

P/Q = (2/1) divided by (pi/2) = (2/1)*(2/pi) = 4/pi

Answer: 4/pi which is choice A

Hey there :)

First thing you want to do is find the y intercepts of the given x's

[tex](\frac{3\pi }{2} , 1)[/tex] & [tex](2\pi,3)[/tex]

x1=3pi/2

y1=1

x2=2pi

y2=3

Now you are going to use the slope formula to find the average rate of change, The formula is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\frac{3-1}{2\pi-\frac{3\pi }{2} } =\frac{2}{\frac{\pi }{2} }=\frac{4}{\pi }[/tex]

And now you have your answer.

[tex]\frac{4}{\pi }[/tex]
