    (-3, 4)

    Step-by-step explanation:

    y = - x² - 4x + 1

    y - 2x = 10

    Solve the system of equations using substitution or elimination. Using substitution:

    (-x² - 4x + 1) - 2x = 10

    -x² - 6x + 1 = 10

    -x² - 6x - 9 = 0

    x² + 6x + 9 = 0

    (x + 3) ² = 0

    x + 3 = 0

    x = - 3

    y = 4

    The solution is (-3, 4).
