 Question 111363: Solve each of the following systems by graphing. x-2y=8 3x-2y=12 I need to see this worked out. I know I need to convert to slope intercept form. So the first one I would do x-2y=8 -x -x -2y= -x+8 divide by -2 on both sides y= x/2 + 4 SO I would start at the plot 0,4, then plot over 2 and up 1, so 2,5?? Then 3x-2y=12 -3x -3x -2y= -3x + 12 divide by neg. 2 on both sides y= 3/2x - 6 so the second set of points would be (0, -6), and (2,3)? Is that correct, and then find the point they intercept which would be never? Click here to see answer by jim_thompson5910(28595)
