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
