A line is drawn through (-7, 11) and (8, - 9). The equation

y - 11 = - 4 (x + 7) is written to represent the line. Which

equations also represent the line? Check all that apply.

3y = - 4x + 40

4x + y = 21

4x + 3y = 5

-4x + 3y = 17

    4x + 3y = 5

    Step-by-step explanation:

    Gradient = - 9 - 11 / 8 + 7

    = - 4/3

    Equation of the line ...

    y = mx + c

    y = - 4/3 (x + 7) + 11

    Multiplying through by 3 ...

    3y = - 4x - 28 + 33

    3y = - 4x + 5

    4x + 3y = 5
