Her answer is wrong because she the object cannot hit the ground at negative seconds. She could’ve have used other methods because she used the quadratic formula. The advantages is that it works for every situation. The disadvantages is that it takes longer. She should’ve used a different method.
Step-by-step explanation:
The first number in the bracket is the x coordinate, the second is the y
So substitute the x and y in to get

3x + 5 (first plug in 2 for x )
3(2) + 5 =
6 + 5 = 11
