Sasha is tracking the results of the water balloon contest. She wants to determine how high Maggie's balloon is when it is directly over the 2-yard line of the field. She knows the equation is y = - x + 17x - 42

Maggie's ballon is 12 high.

Step-by-step explanation:

We are asked to find the y-value, and the x-value is given:

Plug the values in to solve for y.

y = - (2) ^2 + 17 (2) - 42 y

= - (4) + 34 - 42 y

= - 4 + 34 - 42 y

= - 12

The negative sign tells the direction. It is negative because the ballon is in the opposite direction.
