The point (0,0) is a solution to which of these inequalities?

Answers

The point (0,0) is a solution of (y - 5 < 3x - 4) and this can be determined by substituting the value of (x = 0) and (y = 0).

Given :

Point  --  (0,0)

Check all the options in order to determine the inequalities whose solution is (0,0).

A) y + 5 < 3x - 4

Substitute the value of (x = 0) and (y = 0) in the above in equality.

5 < -4 which is not true. Therefore, this option is incorrect.

B) y - 4 < 3x - 5

Substitute the value of (x = 0) and (y = 0) in the above in equality.

-4 < -5 which is not true. Therefore, this option is incorrect.

C) y + 5 < 3x + 4

Substitute the value of (x = 0) and (y = 0) in the above in equality.

5 < 4 which is not true. Therefore, this option is incorrect.

D) y - 5 < 3x - 4

Substitute the value of (x = 0) and (y = 0) in the above in equality.

-5 < -4 which is true. Therefore, this option is correct.
