Question

calcule a equacao reduzida .reta no caso A(3,2) eB(0,1)

Answer 1

$\boxed{y-y_o=m(x-x_o)}\\\\ m = \frac{\Delta\ y}{\Delta\ x}\\\\ m = \frac{1-2}{0-3} = \frac{-1}{-3} = \boxed{\frac{1}{3}}$

$y-1 = \frac{1}{3}(x-0)\\\\ y-1 = \frac{1x}{3}\\\\ \boxed{y=\frac{1x}{3}+1}$

Answer 2

calcule a equacao reduzida .reta no caso A(3,2) eB(0,1)
 


    a =  y2 - y1  =  1 - 2  ==> a =  - 1  ==> a =  1
           x2 - x1      0 - 3                 -3                3


        1 . (0) + b = 1  ==> b = 1
         3



        y =   1x + 1
                 3
