(3, −9)

Equation Form:

x = 3, y = −9

Step-by-step explanation:

Point Form:

10 Boys

Step-by-step explanation:

10 boys prefer the Ferris wheel because the total amount of boys is 35, but 23 of those 35 boys prefers the Super Slide, meaning what's left is who prefers the Ferris wheel since there are only 2 options for them to choose from.

35 boys - 23 boys (who like the Super Slide) = 10 boys (the remainder who likes the Ferris wheel).
