Dos capitales son entre si como 4 es a 5. Uno se coloca a una taza de interes del 50% anual y el otro al 20%. Despues de cuanto tiempo la relacion de los montos es la inversa de la relacion original de sus capitales ?

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
