Answer
We know that,
x co-ordinate at y-axis = 0.
Let co-ordinates of A are (0, b).
Since,
Line 5x - 2y + 8 = 0, intersects the y-axis at point A(0, b).
∴ Point A satisfies the equation 5x - 2y + 8 = 0.
Substituting values we get :
⇒ 5(0) - 2b + 8 = 0
⇒ 0 - 2b + 8 = 0
⇒ 2b = 8
⇒ b = = 4.
∴ A = (0, b) = (0, 4).
Hence, Option 4 is the correct option.
