You can put this solution on YOUR website!
LINES ARE PARALLEL IF THEIR SLOPES ARE EQUAL.
EXAMPLE:
Y=3X/5+3 (RED LINE)
Y=3X/5-4 (GREEN LINE)
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+3x%2F5+%2B3%2C+3x%2F5+-4%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions 3x/5 +3 and 3x/5 -4).
