To determine who is correct, we need to substitute the given coordinates into both equations and see if they satisfy the equations.Let's start with Jane's solution
:Substituting
and
into the first equation:
This is not true, so Jane's solution is incorrect.Now let's try Maverick's solution
:Substituting
and
into the first equation:
This is true. Now let's substitute
and
into the second equation:
This is also true, so Maverick's solution is correct.Therefore, the correct answer is A) Maverick is correct.
