Question

On what point will the line x-y=8 intersect y -axis

Answer 1

x-y =8 will intersect y axis when x=0...therefore the eq will intersect y axis at (0,-8)
 

Answer 2

Answer:

x - y = 8 will interest at y axis only when x = 0

So

0 - y = 8

y = -8

Therefore the intersection point is (x, y)

(0, -8)

Hope it helps
