Answer these from question 18 to 21. Don't give irrelevant ans . Proper answer will be marked as brainliest​

Answer 1

Step-by-step explanation:

18. b) y=0

equation of x axis means there is no y axis, hence y=0.

19. b) (0,y)

Any point on y axis means it will only have its y coordinate. hence x=0 as no x coordinate.

20. c) x+y = 7

x=5 and y=2 satisfy this equation as 5+2 = 7.

21. d) on x axis.

If y coordinate is 0 , then there is only x coordinate left , hence point will lie on x axis.
