    Point A has the x coordinate of -3. Plug this value into the equation to find y. y = -4.3x y = -4.3*(-3) ... replace x with -3 y = 12.9 So when x = -3, y = 12.9 giving the complete point A(-3, 12.9). I'll let you do point B.

    after that, I multiplied -4.3 by -3 to get 12.9

    that's what -4.3x means it means "take -4.3 and multiply it with some number x" x in this case is -3
