Question

(1,2); (3,-4); (-2,-3); (4,0); (0,-5) in which axis or on which a-axis do the following points lie ?

Answer 1

Just divide xy axis in four parts
I part = + x, +y (1, 2)
II part = - X, +Y
III part = - X, - Y (- 2, - 3)
IV part = + X, - Y (3, - 4)
V part = (X, 0) on X axis (4, 0)
VI part = (0, Y) on Y axis (0, - 5)
