Question

i really need help on how to figure this out??

Answer 1

How much does he start with?

Answer 2

he started with 1200?

Answer 3

so the initial value is \((0,1200)\)

now can you tell me slope of the line going through those two points?

Answer 4

hmmm, can you tell me how i would figure that out?

Answer 5

First notice that since he started the business in 2005 that we will call that year 0 of the business, then we have that 2008 is year 3.

This is why we have initial values \((0,1200)\)

so we see that we have two points \((0,1200),(3,1350)\)

so we find the slope of the line going through those two points with \(\frac{1350-1200}{3-0}=50\)

Answer 6

Sope intercept form is \(y=mx+b\) and we know the slope is \(50\) so we have \(y=50x+b\), but since we have initial value \((0,1200)\) our y intercept is \(1200\). Thus we have \(y=50x+1200\)

Answer 7

ohhhh!!!! thank you! that makes sense!
