Question

Determine a equação reduzida da reta R que passa pelos pontos A(5,1) e B(3,-2)

Answer 1

m=yA-yB/xA-xB = 1+2/5-3= 3/2

y = m.(x-xA) +yA

y = 3/2.(x-5) +1

y = 3x/2 -15/2 + 2/2

y = (3/2)x - 13/2

Answer 2

Resposta:

$\left[\begin{array}{ccc}x&y&1\\5&1&1\\3&-2&1\end{array}\right] =0\\\\x+3y-10-3-5y+2x=0\\3x-2y-13=0\\2y=3x-13\\\\y=\frac{3x}{2}- \frac{13}{2}$
