what is the rate of change between (7,15.75) and (3,8.75)
To find the rate of change between two points, we can use the formula:
Rate of change = (y₂ - y₁) / (x₂ - x₁)
Given the points (7, 15.75) and (3, 8.75), we can substitute the values into the formula:
Rate of change = (8.75 - 15.75) / (3 - 7)
Simplifying further gives:
Rate of change = (-7) / (-4)
Finally, dividing gives us the rate of change:
Rate of change = 7/4
Therefore, the rate of change between (7, 15.75) and (3, 8.75) is 7/4 or 1.75.
