I am working on a problem. I am trying to get an equation for this linear line with these traits:

slope = 5/6

linear equation that passes through [1,3]

therefore using this formula

y=mx+b

3=5/6[1]+b

b=13/6

therefore, the equation is

y=5/6[x] + 13/6

However, the answer given is

y - ( 3 ) = (5/6) ( x - ( 1 ) ) ,

or

y = (7/6) x + (13/6) .

Any pointers,

Thanks, Tim
