The midpoint of ab is m (-3,-3) if the coordinates of a are (-8,-2)what are the coordinates of b

The coordinates of B would be (2, -4)

In order to find this, we need to know that the value of M's points will always be the average of A and B's points. This is because it is the midpoint. Therefore we can use the following formula.

Value of x

(A + B)/2 = M

(-8 + B)/2 = -3

-8 + B = -6

B = 2

Then we can do the same for the y values

Value of y

(A + B)/2 = M

(-2 + B)/2 = -3

-2 + B = -6

B = 4

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
