To determine the whether the ordered pair satisfies the equation:
⇒ we must plug in the values
⇒ since coordinates are (x,y) ⇒ (2,1)
⇒ there we must plug 2 into the 'x' position in the equation
⇒ and 1 into the 'y' position in the equation
Let's try the first equation:

- Ordered pair satisfies first equation
Let's try the second equation

- Ordered pair satisfies second equation
Thus ordered pair satisfies the following system of equations
Answer: Yes
