Question

a equação da reta com coeficiente angular igual a $\frac{-4}{5}$ e  que passa pelo ponto P (2,-5)”

a) 4x + 5y + 12 = 0

b) 4x + 5y + 14 = 0

c) 4x + 5y + 17 = 0

d) 4x + 5y + 16 = 0

e) 4x + 5y + 15 = 0

Answer 1

y+(-5) = -4/5 . (x+2)
5y - 25 = -4x - 8
5y -25 + 4x + 8 = 0
4x + 5y -17 = 0
