can someone please correct this for me. i have to graph: y = 3/4x + 2 so the points i got for plotting is: (-4,-1),(0,2),(4,5) then i just connect the points to get the line. If they plot on a line the answer is correct. y= 3/4 x + 2 is a line, and all

can someone correct me: i have to graph i have the inequalities: 3x -6y = 9 x -2y = 3 what i have is the points to plot if my y = -3/2 and my x = 0 therefore: (0,-1.5) and (0,0) No. If y=0, then x=3 . Check that.

is this correct: solve: 5(x-2)^2=3 My answer: (10 +/- sqrt 15)/(5) looks like you expanded, then used the formula and you got the right answer properly reduced. I think you are getting this!!! I don't want to confuse you but I would have done the

IS THIS CORRECT NOW. solve by using the quadratic formula. x^2 = -5-5 My answer: x = (-5 +- SQRT (5))/(2) I don't see any x term, so b is zero. sorry it suppost to read that first -5x-5
