Answer:
(1,-4)
Step-by-step explanation:
Given:- A(-5,4)
and B(7,-8)
so, x1 = -5 y1 = 4
x2 = 7 y2 = -8
to find:- the coordinate of the mid point of the line segment.
we use mid point formula,
let, the point be (x,y)
than,. x = x1 + x2 / 2
x = -5+7 / 2
x = 2/2
x = 1
similarly...,
y = y1 + y2
y = 4 + (-8)
y = 4 - 8
y = -4
therefore, the coordinates of its mid-point are (1,-4)
