    We have been given a function f(x) = 5x - 6. We are asked to choose the point from given choices, which is not a solution of given function.

    Let us check each given point one by one.

    A. (3,9)

    f(x) = 5x - 6

    9= 5(3)-6

    9=15-6

    9=9

    Since both sides of function are equal, therefore, point (3,9) is the solution of our given function.

    B. (1,-1)

    f(x) = 5x - 6

    -1= 5(1)-6

    -1= 5-6

    -1=-1

    Since both sides of function are equal, therefore, point (1,-1) is the solution of our given function.

    C. (5,19)

    f(x) = 5x - 6

    19= 5(5)-6

    19= 25-6

    19=19

    Since both sides of function are equal, therefore, point (5,19) is the solution of our given function.

    D. (4,10)

    f(x) = 5x - 6

    10= 5(4)-6

    10= 20-6

    10\neq 14

    Since both sides of function are not equal, therefore, point (4,10) is not a solution of our given function and option D is the correct choice.
