Question

Find the midpoint of CD.M = (x¹+x2, ₁+2)X1+X2AC = (1,9) and D = (7,-7)([ ? ],[_])Enter the number that belongs in the green box.Enter

Answer 1

Given:

C = (1,9) and D = (7,-7)

Required:

Find the midpoint of CD.

Step-by-step explanation:

`C=(1,9)\text{ D=\lparen7,-7\rparen}`
`\begin{gathered} let\text{ x1=1, y1=9} \\ \\ let\text{ x2=7, y2=-7} \end{gathered}`

Midpoint of CD is

`\begin{gathered} M=((x1+x2)/(2),(y1+y2)/(2)) \\ \\ M=((1+7)/(2),(9-7)/(2)) \\ \\ M=(4,1) \end{gathered}`

Required answer:

(4,1)
