Question

dados os pontos A (3,-2)e B (-1/2,-4).segmento AB determine o ponto médio entre eles:

Answer 1

$\\ Pm = \frac{(ax+bx, ay+by)}{2} \\ \\ Pm = \frac{(3+(- \frac{1}{2}), -2+(- 4) }{2} \\ \\ Pm = \frac{ (\frac{6-1}{2} , -6)}{2} \\ \\ Pm = \frac{ (\frac{5}{2} , -6)}{2} \\ \\ Pm = \frac{( \frac{ \frac{5}{2} }{2}, \frac{-6}{2} )}{y} \\ \\ Pm = ( \frac{5}{4} , -3)$

Answer 2

Angela,
Vamos passo a passo

                  $M( \frac{3+(- \frac{1}{2}) }{2} , \frac{-2+(-4)}{2} ) \\ \\ M( \frac{ \frac{5}{2} }{2} , \frac{-6}{2} ) \\ \\ M( \frac{5}{4} ,-3)$
