here is your answer

Answer 2

(1) (0,-5) lies on y-axis.

$\tt \large \therefore (1) \longrightarrow(c)$

(2) (4,-8) lies in IV quadrant

$\tt \large \therefore (2) \longrightarrow(d)$

(3) (-2,8) lies in II quadrant

$\tt \large \therefore (3) \longrightarrow(a)$

(4) (5,0) lies on x - axis

$\tt \large \therefore (1) \longrightarrow(b)$

[ For better understanding please refer rough diagram of graph where I have plotted these points. ]

$\tt \large \red{Additional-Information :}$

The exact location of a point on a plane is presented or depicted in the form of (x, y) .

Here x and y are known as the coordinates of the point.

Abscissa :- It lies on x- axis ( horizontal line )

Ordinate :- It lies on y - axis ( vertical line)

Cartesian plane is divided into four quadrants :-

Quadrant 1 :- (+x, +y) ⟹ In Quadrant 1 both abscissa and ordinate are positive.

Quadrant 2 :- (-x, +y) ⟹ In Quadrant 2 abscissa is negative and ordinate is positive.

Quadrant 3 :- (-x, -y) ⟹ In Quadrant 3 abscissa is negative and ordinate is also negative.

Quadrant 4 :- (+x, -y) ⟹ In Quadrant 4 abscissa is positive and ordinate is negative.
