Find the midpoint of A and B where A has coordinates (2,9)and B has coordinates (7,4)

(9/2, 13/2).

Step-by-step explanation:

The midpoint of (x1, y1) and (x1, y2)  is (x1+x2)/2 , (y1+y2)/2.

The midpoint is  (2+7)/2 , (9+4) / 2.

= (9/2, 13/2).

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
