Question

Point A is at (-1,-9) and Point B is at (2,4). What is the midpoint of line segment AB

Answer 1

The answer to your question is (1/2, -5/2)

Explanation:

Data

A = (-1, -9)

B = (2, 4)

Formula of midpoint

Xm = (x1 + x2) / 2

Ym = (y1 + y2)/2

x1 = -1 y1 = -9 x2 = 2 y2 = 4

To solve this problem just substitute the values in the formula and simplify.

Xm = (-1 + 2) / 2

Ym = (-9 + 4) / 2

-Simplify

Xm = 1/2

Ym = -5/2

-Solution

Midpoint (1/2, -5/2)

Answer 2

Midpoint( .5,-2.5)

Explanation:

To find the midpoint, add the x coordinates and divide by 2 and then add the y coordinates and divide by 2

x: (-1+2)/2 = 1/2=.5

y: (-9+4)/2 = -5/2 = -2.5

Midpoint( .5,-2.5)
