Equaling the equations, it is found that the cars hit each other at: (-1,-4) and (1,-6).

---------------------------------

For the first car, we have that:

x + y = -5

Thus:

y_1 = -5 - x

---------------------------------

For the second car:

y_2 = x^2 - x - 6

---------------------------------

They meet at the the values of x for which:

y_1 = y_2

Thus:

-5 - x = x^2 - x - 6

x^2 - 1 = 0

x^2 = 1

x = \pm \sqrt{1}

x = \pm 1

  • When x = 1, they meet at y = -5 - 1 = -6
  • When x = -1, they meet at y = -5 - (-1) = -5 + 1 = -4

Thus (-1,-4) and (1,-6).
