Answer:
(B) only I and II
Step-by-step explanation:
An odd relation is symmetrical about the origin. All of the relations are odd.
An even relation is symmetrical about the y-axis. Only the first two relations are even.
_____
The graph shows the first relation is that of a circle. It is symmetrical about its center at the origin and about any diameter, including the y-axis.
The second relation is a degenerate hyperbola. It graphs as the pair of lines y=x and y=-x. It is symmetrical about both the origin and the y-axis. (It also has other lines of symmetry.)
The third relation is a line with slope -1 (represented by dots). It is symmetrical about the origin, but not the y-axis. It is only an odd relation.

Given
The equations are;
A point of intersection is a point where two lines or curves meet.
There are two methods to find a point of intersection graphically by graphing the curves on the same graph and identifying their points and another one is to solve the equation and find the value of x and y.
Adding both the equation
Substitute the value of y in the equation
Hence, there are zero points of intersection.
