Answer:

y=-5x-21 (D)

Step-by-step explanation:

Since the two lines parallel, their gradient must be equal

m1=m2=m=-5

y − y1 = m(x − x1)

And since the line passes trough pint (-4,-1), therefore

y –(-1) = -5(x – (-4))

y+1=-5(x+4)

y+1=-5x-20

y=-5x-20-1

y=-5x-21

kozerog [31]

Answer:

$y=4\cdot{x}+20$

Step-by-step explanation:

Let the regresssion line be linear because of a constant amount of money coming in. Let y be the total amount of money in the box and x the weeks of adding to the box:

$y=m\cdot{x}+c$

We know that he puts $20 in the box from his birthday and $4 every week for x weeks. Therefore the total amount of money will be:

$y=4\cdot{x}+20$
