Question

Find the midpoint of the line segment joining (3, -4) and (7, 2).

Answer 1

do you know midpoint formula? :)

Answer 2

no

Answer 3

\[\LARGE \left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right) \]

Answer 4

can you substitute

Answer 5

let me try to solve it.

Answer 6

5. -1?

Answer 7

that's correct... well done :)

Answer 8

I got this answer 3 + 7/2 , 2+ (-4)/2
10/2 , -2/2
5, -1

Answer 9

that's it. \[\LARGE \begin{array}{l}\left( {\frac{{{x_1} + {x_2}}}{2},\frac{{{y_1} + {y_2}}}{2}} \right)\\\left( {\frac{{3 + 7}}{2},\frac{{ - 4 + 2}}{2}} \right)\\5, - 1\end{array}\]

Answer 10

the same :)...

Answer 11

Thank you but what about this formula 1/2 (3+7), 1/2 (-4 +2)? Is this also right?

Answer 12

btw, I like the formula you have mentioned, it is much easier and short. Thank you so much :)

Answer 13

\[\LARGE \frac12 (3+7)=\frac{3+7}{2}\]

those are the same... :)
