Question

Find the midpoint between each pair of points (7,-2) and (-4,2)

Answer 1

Use midpoint formula: (x+x/2, y+y/2)
Substitue: (-4+7, 2-2/2)
Add: (3/2, 0/2)
Answer: (3/2, 0) or (1.5, 0)

Answer 2

the midpoint between each pair of points  

(7,-2) and (-4,2)

To find midpoint we use midpoint formula

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

Here (x1,y1) is (7,-2)  and (x2,y2) is (-4,2)

$\frac{(7+(-4))}{2} , \frac{(-2+2)}{2}$

$\frac{3}{2} , \frac{0}{2}$

Midpoint is $\frac{3}{2} , 0$
