What is the rate of change between the interval x= pi and x= 3pi/2

or 1.9099

Step-by-step explanation:

Look for y values at each of those given values of "x" and apply the slope formula.  When x = pi. y = -1 so the coordinate is .  When x = 3pi/2, y = 2 so the coordinate is

Plug those values into the slope formula:

You need a common denominator of pi:

Do the math on that to get a slope of

do i do it on a graph?

step-by-step explanation:

the correct answer is d
