Question

What are the coordinates of the midpoint of the line segment whose endpoints are (2a,3b) and (6a,b)?

A) (4a,2b) B) (3a,2b) C) (2a,b) D) (2b,4a)

Answer 1

The co-ordinates of midpoint(x,y) on the line segment with end-points (x1,y1) and (x2,y2) is just the average of co-ordinates, given by :
\(\large x=\frac{x_1+x_2}{2}\)
\(\large y=\frac{y_1+y_2}{2}\)
now,just put the values and find the co-ordinates of midpoint (x,y).

Answer 2

A?

Answer 3

I got 4a,1.5b

Answer 4

Answer 5

4a is correct
(3b+b)/2 = 4b/2 = 2b

Answer 6

So, A is right?

Answer 7

yes! :)

Answer 8

Yay!
