Question

2) Determine o coeficiente angular de m.( m= $\frac{y2-y1}{x2-x1}$) a) A (2,3) e B (4,7) b) A (2,-3) e B (-4,3)

Answer 1

Explicação passo-a-passo:

a)

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\\\Rightarrow m=\dfrac{7-3}{4-2}\\\\\\\\\Rightarrow m=\dfrac{4}{2}\\\\\\ \Rightarrow m=2$

b)

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\\\Rightarrow m=\dfrac{3-(-3)}{-4-2}\\\\\\\\\Rightarrow m=\dfrac{6}{-6}\\\\\\ \Rightarrow m=-1$
