    Answer:

    C

    Step-by-step explanation:

    original formula is: y – y1 = m (x – x1) ordinates= (x1, y1)

    insert the a corresponding x and y coordinate:

    y + 3 = -2 (x + 9)

    Don’t forget to change the signs depending on whether their positive or negative:

    (3, -9) since 3 is positive but there is a minus in the formula it would be -3

    since -9 is negative and in the equation there’s a minus sign you would change it to positive. (negative times a negative equals a positive)
