Question

calcule a distancia entre o ponto A(1,4) e a reta r=4x+3y-1=0

Answer 1

Olá!!

Resolução!!

A ( 1, 4 ) e r : 4x + 3y - 1 = 0

``````````````````````````````````______
D = |ax + by + c|/√a² + b²
``````````````````````````````````______
D = |4x + 3y - 1 |/√4² + 3²
`````````````````````````````````````_______
D = |4 • 1 + 3 • 4 - 1|/√16 + 9

D = |4 + 12 - 1|/√25

D = |15|/5

D = 15/5

D = 3

R = A distância é 3 u.

Espero ter ajudado!!
