3. Find the coordinates of D, the midpoint of AB.

The mid-point D is (6,3)
Step-by-step explanation:
The mid-point is the point on a line that divides the line in two equal parts
The given two points are:
A(4,5)=(x1,y1)
B(8,1)=(x2,y2)
D is the mid-point
So,
[tex](x_D,y_D)=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})\\(x_D,y_D)=(\frac{4+8}{2}, \frac{5+1}{2})\\(x_D,y_D)=(\frac{12}{2}, \frac{6}{2})\\(x_D,y_D)=(6, 3)[/tex]
The mid-point D is (6,3)
