First line: \;y=0.5x+8

If you want another line perpendicular to this one, the product of the slopes must be equal to -1.

For the first line: a = 0.5
Then for the perpendicular one, it shloud be a = -2

-2×0.5 = -1

<u>We have then two lines:</u>

y=0.5x+8\\&#10;y=-2x

Sorry if my english is not quite good..

Juana compró una camioneta 4x4 a S/ 42 000; además, sabe que la camioneta se depreciará (bajará su precio) en forma lineal duran
prohojiy [21]

Answer:

Una relación lineal es de la forma:

y = a*x + b.

donde a es la pendiente y b es la ordenada al origen.

en este caso, y es el precio de la camioneta, x es el numero de años que pasaron, a es la razon de depreciación de la camioneta y b es el precio inicial de la camioneta, b = $42,000.

Sabemos que después de 5 años, el precio de la camioneta es 21,000, entonces podemos resolver:

$21,000 = a*5 + $42,000

a*5 = $21,000 - $42,000 = -$21,000

a = -$21,000/5 = -$4,200

Esto significa que el precio decae $4,200 por año
