# What is the rate of change between the interval x = π and x = three pi over two?

**Solution:**

x_{1} = π and x_{2} = 3π/2

y_{1} = -1 and y_{2} = 2

Rate of change = (y_{2} - y_{1})/(x_{2} - x_{1})

Substituting the values

Rate of change = [2 - (-1)]/ [3π/2 - π]

So we get

Rate of change = 3/(π/2)

Rate of change = 6/π

Rate of change = 1.91

Therefore, the rate of change is 1.91

## What is the rate of change between the interval x = π and x = three pi over two?

**Summary:**

The rate of change between the interval x = π and x = three pi over two is 1.91
