Question

6. Calcule os coeficientes lineares e angulares das retas cujas equações são
$a) \: y = - x - 1$
$b) \: f(x) = \frac{2}{3}x+ 4$
$c) g(x) = 1 + \frac{x}{2}$

​

Answer 1

a) y = - x - 1

... - 1 (coef. angular) e - 1 (coef. linear)

b) f(x) = 2/3 x + 4

... 2/3 (coef. angular) e 4 (coef. linear)

c) g(x) = 1 + x/2

... 1/2 (coef. angular) e 1 (coef. linear)
