U(8, 9) and V(2, 5) are the endpoints of a line segment. What is the midpoint M of that line segment?

Pavel [41]

Answer:

The midpoint M is (5,7)

Step-by-step explanation:

$m = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

U(8,9)

V(2,5)

m = [(8+2)/2 , (9+5)/2]

= [(10/2) , (14/2)]

= (5,7)

4x+5 = 8x - 11
4x - 8x = -11 - 5
-4x = -16
x = 4

4x+5 = 4(4) +5 = 21
8x - 11 = 8(4) - 11 = 21

<RST = 21 + 21 = 42
