For the system of equations for three points [(1, -2) , (3, 5) , (7, 8)]my solutions were as follows:
a = -.4583
b = 5.3332
c = -6.8749
Each variable was substituted with success, apart from the last equation.
49a + 7b + c = 8
-> 49(- .4583) + 7(5.3332) + (-6.8749) = 8.0008
Is this minute discrepancy common? Are my values still considered accurate regardless?

Your numbers were accurate only to the fourth decimal place. So a discrepancy in the fourth decimal place would be expected in your result.
