Question 250706
Step #1 - solve 3x + 4y -8 = 0 for y.
Y = -(3/4)X +2.
STEP #2 - find the slope based on the equation from STEP #1. M = (-3/4).
STEP #3 - parallel lines have the same slope. The slope you have from STEP #2 is the slope you want. m = (-3/4).
STEP #4 - using the slope from STEP #3, pick a point (2,3) and put those into 
Y = mX + b. Solve for b.
3 = (-3/4)(2) + b.
b = 9/2.
STEP #5 - write the equation.
Y = (-3/4)X + 9/2.
