Finding the Equation of a Line

[Super-Id]

I am trying to find the equation of the line
Y-56 = 28 19/20(x-2)
And just to clarify in case I wrote that wrong, 28 and 19/20 is the gradient.
I got this from the rule that
Y-Yi = m(x-xi)
But I'm at a total loss as how to simplify this into a more palatable form, ie. as a variation on
y = mx + b.

Desperately needing a bit of help here ASAP, so thanks for your time.
Regards,
Alice.

Mixed fractions ore of virtually no value.

28+(19/20) = (20*28 + 19)/20 = 579/20

See if that gets you anywhere.
