Aadya and Ethan like playing with remote control cars. They use a rectangular coordinate system in the play area. Aadya puts her car on A (2,3) and Ethan puts his car on B (9,12). Then the children drive the cars toward each other until the collide. What is the sum of the coordinates of the point on which the cars collide if they drive at the same speed?

answer: integers are just whole numbers: positive, negative, and zero.
i = {-∞, -2, -1, 0, 1, 2, 3, ∞}
let x = 1st integer
let y = 2nd integer
x = 3y + 17 {equation 1}
xy = -24 {equation 2}
substitute 3y+17 in place of x n equation 2
and solve for y.
(3y+17)y = -24
3y2 + 17y = -24
3y2 + 17y + 24 = 0
from quadratic equation:
y = [-17±√(172-4(3)(24))]/(2(3))
y = (-17 ±√1)/6
y = (-17+1)/6 or y = (-17-1)/6
y = -16/6 or y = -18/6
y = -2 2/3 or y = -3
since we are dealing with
y = -3
x = 3y+17 = -9+17 = 8
the integers are -3, 8
