Question

A small college had 2546 students in 2002 and 2702 students in 2004. If the enrollment follows a linear growth pattern, How many students will the collage have in 2008?

Answer 1

Let y = amount of children.
Let x = years past
Let c = amount of children in 2002.

m = (y-y)/(x-x)
m = (2702-2546)/(2004-2002)
m = 78

y = mx + c
y = 78x + c

your c is always your initial value. SO:

y = 78x + 2546

So basicly this graph tells us that each year there are 78 people coming to the school. 6 years will have past since 2002. So we just change x to 6.

y = 78*6 + 2546.
y = 3014

Does this make sense?

Answer 2

x should really be years since 2002. Sorry.
