Question

If (a, b) is a point that lies on the y axis what is the value of a

Answer 1

value of a = 0

Explanation:

becaus if the point Lies on y Axis then x=0

a=x

b=y

if IT the point was on x Axis then

y=0

the formule y= a.x+b

is used when a is asked

in this case we don't need to use the formule because a =y

if the point Lie on y

Answer 2
