Answer:
The correct answer is "9√2 units".
Step-by-step explanation:
The given equations are:
⇒
...(equation 1)
⇒
...(equation 2)
According to the 2nd equation, we get
⇒ 
⇒ 
On substituting the value of "y" in the 1st equation, we get
⇒ 



On taking common, we get

On applying factorization, we get





or,


Now,
The points are:
(-7, 12) = (x₁, y₁)
(2, 3) = (x₂, y₂)
By using the distance formula, the length of chord will be:
= 
On substituting the values in the above formula, we get
= 
= 
= 
=
units
