If the area of \( \Delta ABC \) with vertices \( A(3, 1) \), \( B(-2, 1) \) and \( C(0, k) \) is \( 5 \) sq. units, then values of \( k \) are :
Show Hint
Don't forget to include the \( \pm \) sign when removing the area modulus context. Omitting the negative case will cause you to miss one of the valid solution coordinates.
