Question

DETERMINE A EQUAÇÂO GERAL DA RETA QE PASSA PELOS PONTOS. A) A (-3,5) E B (3,-1) B) A (-1,1) E B (1/4,3/4)?

Answer 1

A)

A(-3,5) e B(3, -1)

m = (5 + 1)/((-3-3) = -1

y - 5 = - *(x + 3)

y - 5 = -x - 3

x + y - 2 = 0

B) A(-1,1) e B(1/4,3/4)

m = (1 - 3/4) / (-1/4 - 1) = (1/4)/(-5/4) = -1/5 

y - 1 = -1/5 * (x + 1)

5y - 5 = -x - 1

x + 5y - 4 = 0
