Question

The coordinates of quadrilateral FGHJ are F(-5, -3), G(-3, 3), H(3, 5), and J(7, -1).

Answer 1

To find the midpoint of line FG, we have to use the following midpoint formula , which is

$(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2})$

In the given question,

x1= -5, y1= -3 , x2=-3, y2=3

Substituting the values of x1,y1,x2 and y2 in the formula of the midpoint, we will get

$(\frac{-5-3}{2},\frac{-3+3}{2}) =(-4,0)$

So the midpoint of the given line is (-4,0) and hence the correct option is the first option .
