Set them equal to one another and solve for x.
cross%282x-2x%29%2B1=cross%282x-2x%29%2B8Subtract 2x from both sides
1=8This answer tells us that there is no solution. Also since there is no solution, the lines do not intersect.
graph%28+300%2C+200%2C+-5%2C+5%2C+-5%2C+5%2C+2x%2B1%2C+2x%2B8+%29
Notice these two lines are parallel and never cross each other.
