Question

Determine o coenficiente angular da reta que passa pelos pontos (-1,3) e (4,-5).

Answer 1

m = (y2 -y1) / ( x2 - X1)

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

m = -8 / 5


logo, o coeficiente angular vale -8/5

Answer 2

Boa tarde Raiane

sendo A(-1,3), B(4,-5) 

coeficiente angular

a = (Ay - By)/(Ax - Bx)

a = (3 + 5)/(-1 - 4)

a = -8/5
