Solve for y by 1.) subtracting 3x ... -y=-3x+2
2.) divide by -1 ... y=3x-2
Then graph y=3x-2. 3 is the slope and -2 is the y-intercept
3xy - 3xy = 0
y equals x-4 plus 2 is the same as y = x-2. You just translate the graph of y=x, 2 units to the right, OR 2 down.
3xy-2x-4=0,... so taking the dirividive of y using newtons it would be(3y)(3xy') -2=0 which could be called9 xyy'-2=0.. remember you Are trying to isolate the y prime. so bring the 2 over first.9xyy'=2.....then divide by 9xyy'=(2)/(9xy).....so then just plug in your variables and presto

y=x+1 there for answer is 2
