Answer:

A. (1.55, 2)

Step-by-step explanation:

The formula to apply when finding the midpoint of a segment where the coordinates of the end points are given is;

$midpoint=(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )$

where (x₁,y₁) and (x₂,y₂) are the coordinates of the end points

Given;

x₁= -0.4 ,y₁=2.5, x₂=3.5, y₂=1.5 then applying the formula for midpoint

$=(\frac{-0.4+3.5}{2} ,\frac{2.5+1.5}{2} )\\\\\\=(\frac{3.1}{2} ,\frac{4.0}{2} )\\\\\\=(1.55,2.0)$

Subtract the numbers.

10 - 8 = 2

Divide it to the smaller number:

2 / 8 = 0.25

Multiply by 100:

0.25 * 100 = 25%
