Question

A soma do coeficiente angular com o coeficiente linear da reta que passa pelos pontos A(1, 5) e B(4, 14) é:

Answer 1

M=14-5/4-1
M=3

y-5=3.(x-1)
y=3x-3+5
y=3x+2

Portanto:
Coef. Angular = 3
Coef. Linear = 2
3+2=5

Answer 2

y2-y1/x2-x1=>
14-5/4-1=>9/3=>3 coeficiente angular

y-y0=a(x-x0)
y-5=3(x-1)
y-5=3x-3
y=3x+2

somas de a+b=>
3+2=5
