Question

calcule os coeficientes angulares as retas que passam pelos pontos
A a(-1,3) b(-4,3)
B c(3,2) d(-3,2)
C e(2,3) f(-4,3)
D g(200,100) h(300,80)

Answer 1

A) $m=\frac{3-3}{-1+4}=\frac{0}{3}=0$

B) $m=\frac{2-2}{3+3} =\frac{0}{6}=0$

C) $m=\frac{3-3}{2+4}=\frac{0}{6}=0$

D) $m=\frac{80-100}{300-200}=\frac{-20}{100} =-\frac{1}{5}$
