Question

(2,-1)is the solution of. [options a) x-y=2. b) x-y= 1. c) x-y=3. d) x+y=3]​

Answer 1

Answer:

c) x - y = 3

Step-by-step explanation:

Coordinates are written in the format (x, y).

So, comparing with the given solution,

(x, y) = (2, -1)

∴ x = 2

∴ y = -1

2 -(-1)

= 2 + 1

= 3

Hence, the answer is:

c) x - y = 3
