While eating a slice of pizza with her friends, Shefali noted that it is shaped like a triangle. She questioned her friends about computing the area of the pizza slice using determinants, given the vertices of the slice. If area of a triangle shaped pizza slice is \(35\) sq. units with vertices \((2, -6)\), \((5, 4)\) and \((k, 4)\), then \(k\) is:
- 12
- −2
- −12, −2
- 12, −2
Answer
(D) 12, −2
