Notice that you have a common factor of 2 in both of these terms. So, you can factor out 2 out of each term and have a product:
2x + 2y = 2(x+y)

2x+2y
6x-2x-6xy-2x-2y4x-2y=2x-2y-14xy
10x - 5y + 2x - 3y = 12x - 8y
If: 12 = 2y+x then y = -1/2x+6 So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines
3x-2y+9+9y-x = 2x+7y+9
