Question 31203: Please find the equation of the line that passes through (2,1) and is parallel to the line: 4x-2y=3
Answer by troyapplehelen(46)   (Show Source):
You can put this solution on YOUR website! 1. 4x-2y=3 can be rewritten as 4x-3=2y, y=(4x)/2-(3/2)
according line equation, y=mx+b, the slope of line m=2(from 4x/2)
if the line is parallel to the original, the the slope shoulb the same so, the new line equation is y=2x+b.
2. now, find "b" by substituting (2,1) into the new line formular y=2x+b.
like, 1=(2 times 2)+b, then "b" is -3.
3. so, the answer is y=2x-3.
