Can someone help me with this word problem:
The median price of a single-family home from 1980 to 1990 can be approximated by P(x)=3421x+61,000 where x=0 corresponds to 1980 and x=10 to 1990.
(a) Interpret the slope of the graph of P. (I get that the slope represents and average increase of $3,421 every ten years...)
(b) Estimate the years when the median price range was from $71,000 to $88,000.
So I understand this would be in equality equation, but I don't know where to start.
HELP!!!!!!!
