Question

podrian ayudarme con esto? a un que sea con la explicación ME URGEE :((

Answer 1

Respuesta:

$1).m = \frac{3 - 1}{ - 1 + 2} = \frac{2}{1} = 2$

$2).m = \frac{1 + 1} {2 + 3} = \frac{2}{5} \\ \alpha = \arctan( \frac{2}{5} ) = 21.8 {}^{ \circ}$

$3).d = \sqrt{ {(2 + 2)}^{2} + {( - 3 - 1)}^{2} } = \sqrt{16 + 16} = \sqrt{32} = 4 \sqrt{2} .$

$4).(x_{pm},y_{pm}) = ( \frac{ - 1 + 3}{2} , \frac{ - 1 + 3}{2} ) \\ (x_{pm},y_{pm}) = (1,1) \\ x_{pm} = 1 \\ y_{pm} = 1$
