Rearrange the equations to show 6y = 3x + 14 and 9y = -18x - 14.
This gives you the gradients of the two straight lines.
y = 3/6 x + 14/6 and y = -18/ 9 x - 14/9.
The first shows a gradient of 3/6 and the second is -18/9. These are called the co-efficients of x in each equation.
The two gradients cancel down to 1/2 and -2.
One is the negative reciprocal of the other, so the two lines are not parrallel. They a perpendicular to each other.
