we are given two points as
(3, 16) and (5, 10)
firstly , we will find slope
slope is m
so, we can use formula

now, we can plug points



we can plug it in y=mx+b
we get

now, we can select any one points
and find b
(3,16)
x=3 and y=16

we can find b

now, we can plug back b
and we get

so, equation is

and
...............Answer
Answer:
0.04 is as close as it gets
Y2-y1 over x2-x1 or you can go onto the calculator and push list and put in the points and it will give you the answer of 68
