Question

Calcule o coeficiente angular da reta que
passa pelos pontos abaixo

f)A(-1,2) B(-6,7)=​

Answer 1

Explicação passo-a-passo:

A fórmula para calcular o coeficiente angular é dada por

                                                 $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

a) A (-2, 3), B (10, -2)

   $m=\frac{-2-3}{10-(-2)}$ → $m=\frac{-5}{10+2}$ → $m=-\frac{5}{12}$

_____________________________________________________

b) A (10, -2), B (13, -5)

   $m=\frac{-5-(-2)}{13-10}$ → $m=\frac{-5+2}{3}$ → $m=\frac{-3}{3}$ → $m=-1$

____________________________________________________

c) A (24, 6), B (4, 12)

   $m=\frac{12-6}{4-24}$ → $m=\frac{6}{-20}$ → $m=-\frac{3}{10}$

____________________________________________________

d) A (0, 4), B (-5, -3)

   $m=\frac{-3-4}{-5-0}$ → $m=\frac{-7}{-5}$ → $m=\frac{7}{5}$

____________________________________________________

e) A (20, -3), B (-3, -2)

   $m=\frac{-2-(-3)}{-3-20}$ → $m=\frac{-2+3}{-23}$ → $m=-\frac{1}{23}$

___________________________________________________

f) A (-1, 2), B (-6, 7)

  $m=\frac{7-2}{-6-(-1)}$ → $m=\frac{5}{-6+1}$ → $m=\frac{5}{-5}$ → $m=-1$
