Question

encontre o coeficiente angular e o coeficiente linear e a equacao da reta que passa pelos pontos(3,-5)e (1,-1)

Answer 1

A(3,-5) e B(1,-1)

m = ( yb - ya ) / ( xb - xa ) = ( -1 + 5 ) / ( 1 - 3 ) = 4/2 = 2

y - ya = m ( x - xa )

y + 5 = 2 ( x - 3 )

y + 5 = 2x - 6

y = 2x - 6 - 5

2x - y - 11 = 0
