    Use: \[\large Distance = \sqrt{(x_2 - x_1)^2+ (y_2 - y_1)^2}\] \[\large x_2 = -4, x_1 = 4, y_2 = 3, y_1 = -3\] Plug in the values and find the distance..

    You are not taking care of negative signs.. \[Distance = \sqrt{(-4-4)^2 + (3 - (-3))^2}\]

    -4 -4 = -8 and: 3 - (-3) = 3 + 3 = 6

    I think I have put square above the brackets in the formula. You have to square them first and then add them..
