What is the equation of the line with the given ordered pairs of (3,5) and (9,7)

(3,5) and (9,7)
leads to
m=%28y%5B2%5D-y%5B1%5D++%29%2F%28x%5B2%5D-x%5B1%5D++%29=%287-5%29%2F%289-3%29=1%2F3%0D%0A

m=%28y%5B2%5D-y%5B1%5D++%29%2F%28x%5B2%5D-x%5B1%5D++%29=%287-5%29%2F%289-3%29=1%2F3%0D%0A

Then
using (3,5)
%0D%0Ay-y%5B0%5D+=+m%28x-x%5B0%5D%29%0D%0A

%0D%0Ay-y%5B0%5D+=+m%28x-x%5B0%5D%29%0D%0A

becomes

%0D%0Ay-5+=+%281%2F3%29%28x-3%29%0D%0A
