    Answer:

    The point is (7,0).

    Step-by-step explanation:

    The equation of a linear function in point-slope form is as follows :

    y-y_1=m(x-x_1) …(1)

    Where

    (x₁,y₁) are the coordinates of the point which  the line passes through it and (x,y).

    Harold correctly wrote the equation y= 3(x–7)

    or we can write it as :

    y-0=3(x-7) …(2)

    Comparing equations (1) and (2), we get :

    x₁ = 7 and y₁ = 0

    So, the point is (7,0).

    The correct option is (c).
