Question

Nolan began with $20 in his bank account and spent $2 each day. The line models the amount of money in his bank account. He incorrectly wrote an equation for the line in slope intercept form as y equals negative 2x + 10.

What is the correct equation for the line in slope intercept form?

What mistake might Nolan have made?​

Answer 1

Answer:

y=-2x+20

Step-by-step explanation

The slope is determined with the "spent $2 each day" which translates to -2x and the y intercept should be how much money he started with($20). It looks like Nolan divided 20/2 to get 10, which would be how many days until he would have no money. Hope this helps!

Answer 2

Answer:

no, its y=-5x+30

Step-by-step explanation:

I just know.
