The average price of tuition and fees at private 4-year colleges and universities increased from $8,500 in 1992 to $24,000 in 2008. Calculate the relative change in price from 1992 to 2008 and compare it to the overall rate of inflation as measured by the Consumer Price Index.

Average tuition and fees in private 4-year colleges and universities increased by %?

1992 CPI - 140.3
2008 CPI - 215.3​

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
