Question

Determine a equação da reta que passa pelos pontos: A (8, 3) e B (-6, -4).​

Answer 1

Resposta:

• $\sf{y=\dfrac{1}{2}x-1}$

Explicação passo-a-passo:

• $\sf{M=\dfrac{(y2-y1)}{(x2-x1)}}$

• $\sf{M=\dfrac{(-4-3)}{(-6-8)}}$

• $\sf{M=\dfrac{-7}{-14}}$

• $\sf{M=\dfrac{7}{14}}$

(Simplificando por sete )

• $\sf{M=\dfrac{1}{2}}$

• $\sf{y-yo=M.(x-xo)}$

• $\sf{y-3=\dfrac{1}{2}.(x-8)}$

• $\sf{y-3=\dfrac{1}{2}x-4}$

• $\sf{y=\dfrac{1}{2}x-4+3}$

• $\underbrace{\sf{y=\dfrac{1}{2}x-1}}$
