Use the midpoint formula to find the midpoint between h(3, 9) and j(9, -2).a. (14, 11)b. (4, 5.5)c. (7, 3.5)d. (6, 3.5)

Hello!

The midpoint formula is basically an average of x and y.

It is also written as: .

With the formula above, we can substitute the given points into the equation, and simplify.

Therefore, the midpoint between points H and J is choice D, (6, 3.5).

look a the sides they are perpendicular
