Question

Given that the coordinates of the points A and B are ( -6, - 9) and ( -4, - 9) respectively. What are the coordinates of the midpoint of AB? 


A ( -2, 0)
B ( - 5, - 9)
C ( 5, 9 )
D ( -10, - 18)​

Answer 1

Answer:

B

Step-by-step explanation:

The midpoint formula is $(\frac{x1+x2}{2} ,\frac{y1+y2}{2} )$

Lets plug in our points:

$\frac{(-6)+(-4)}{2}$=-5 (the x value)

$\frac{(-9)+(-9)}{2}$=-9 (the y value)
