The rate of change of parts produced per hour is 
Explanation:
Let the values in the x axis is represented by Parts.
Let the values in the y axis is represented by Time.
The formula to find the constant rate of change is

Let us substitute the values using the coordinates
and 
Thus, we get,

Simplifying, we have,

Thus, the constant rate of change of parts produced per hour is 
10 3/4 - 6 1/2 the difference between these two will be your answer
1/13. there's 52 cards in a deck and 4 of each card .so 52÷4=13 .1/13
I'm pretty sure you are :)
