What is the midpoint between a (3,4) and b (-3,-6)

Step-by-step explanation:

X: (x1 + x2)/2 = (3 - 3)/2 = 0/2 = 0

y: (y1 + y1)/2 = (4 - 6)/2 = -2/2 = - 1

Midpoint (0,-1)

ANSWER

EXPLANATION

The midpoint formula is given by:

To find the midpoint of the segment joining A (3,4) and B (-3,-6), we substitute the points into the formula:

We simplify to obtain;

This gives us;

The midpoint of line segment AB is (0,-1)
