Interseção com o eixo $$x$$

$$\left(-\frac{b}{a}, 0\right)$$

Exemplo de gráfico: $$f(x) = x - 2$$

corta $$y$$ em $$-2$$ e $$x$$ em $$2$$

Função do 1º grau com $$a = 1$$ e $$b = 0$$

latex="f(x) = x"> , reta passa pela origem

Exemplo: $$f(x) = -x + 4$$

decrescente, corta $$y$$ em $$4$$

Variação de $$f(x)$$ em função de $$x$$

cada unidade em $$x$$ , $$f(x)$$ varia $$a$$ unidades

Exemplo: $$f(x) = 5 - 3x$$

decrescente, corta $$y$$ em $$5$$
