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
