12 in | 11 9/16 in 10 in | 9 3/4 in can you find the rate of change for the two sets of points? is this relation a function?

If we are to treat these as two ordered pairs, then the rate of change is 0.90625

Step-by-step explanation:

To find this, use the slope equation with the ordered pairs.

m(slope) = (y2 - y1)/(x2 - x1)

m = (11 9/16 - 9 12/16)/(12 - 10)

m = (1 13/16)/2

m = 1.8125/2

m = 0.90625

Now we know that this could be a function since we have a constant slope.
