Question

The inequality x - y > 0 is satisfied by point (-1, 1). T/F

Answer 1

-2 is not greater than zero, so, the point don't satisfy the inequality  x - y > 0

Hence correct option is false.

Step-by-step explanation:

We need to identify the point (-1,1) satisfies the inequality  x - y > 0

Solving:

The value of x = -1 and y =1

Putting values in the inequality:

$x-y>0\\-1-1>0\\-2>0\,\,false$

-2 is not greater than zero, so, the point don't satisfy the inequality  x - y > 0

Hence correct option is false.
