Howdy!
using the expression 14.99(n) + 4.99, the total of 3 CDs would cost $49.96.
Answer: 
=====================================
Work Shown:
6x-y = -3 is the same as 6x-y+3 = 0
6x-y+3 = 0 is the form Ax+By+C = 0 with A = 6, B = -1, C = 3.
The distance d that line is from the point (p,q) = (6, 2) is found by the following



So the equations are equal
