Sorry about the handwriting! Simply sub x=0 and y=0 into the line equation obtained to get coordinates for P and Q. Doesn’t matter which letter you assign each coordinate to. To find the length of P and Q, simply use Pythagoras’ theorem. PQ is the hypotenuse of our right angled triangle; our right angle is found at our point of origin. Hence we simply have PQ^2= PO^2 + OQ^2. Be sure to use only positive values in your calculations since we’re only interested in the magnitude of values obtained.
