Hey, I am having a little trouble with a question from the "Equation of a straight line" topic:

Find the gradient of OA. The equation is x-2y=0. The coordinates of O are (0,0). I am sure the solution is fairly obvious but I'm having a little trouble. Cheers!

I'm assuming that x-2y=0 is the equation of the line OA, so the gradient is 1/2
(as x-2y=0 => 2y=x => y=(1/2)x so the gradient is 1/2)
