Write the equation of the line that passes through (2, 3) and is parallel to the line 12x – 5y = 2.

Alexeev081 [22]

   12x - 5y = 2
12x - 12x - 5y = -12x + 2
   -5y = -12x + 2
      -5 -5
      y = 2.4x - 0.4
   y - 3 = 2.4(x - 3)
   y - 3 = 2.4(x) - 2.4(3)
   y - 3 = 2.4x - 7.2
         + 3    + 3
      y = 2.4x - 4.2
