equation of a line: y=mx + b equating your givens: y=3x2 2y=6x3 (divide both sides by 2 to eliminate constant 2. so we will get:) y=3x3/2 lines are parallel.. you can graph it by substituting x. let's say from 3 to 3.. slopes: both slopes are 3.

did you know why i came up with y=3x2 from 3xy=2?

but then wouldn't be y=3x+2 & 2y=6x+3?

because if you transfer a number from other side, the sign will change. let's say 2+3=1 if you transfer 2 to the right side, it will be 3=1+2..

2+3=1.. if you transfer 2 to the right side, it will be 3=1+2

the red line is your y=3x2 and the green line is your y=3x3/2 and for the slope, from the equation y=mx+b, m is the slope. so the slope for the two linear equations is 3. the rest are in the images. :D http://www.fileden.com/files/2007/10/19/1523433/IMG_0022.PNG http://www.fileden.com/files/2007/10/19/1523433/SAM_1559.JPG
