Question 1002775: Please help me solve this: In 2004, the median yearly family income was about $44,000 per year. Suppose the average annual rate of change since then is $1240 per year. Write and graph an equality for the annual family incomes y that are less than the median for x years after 2004.

You can put this solution on YOUR website!
Plot median yearly family income, +I+ on the vertical axis
Plot +x+ years following 2004 on the horizontal axis
+1240+ is the slope
The intercept on the vertical axis is +44000+
--------------------
+I+=+1240x+%2B+44000+
--------------------
If you want to express +I+ as incomes less than
the median for +x+ years after 2004, you
need the inequaity:
+I+%3C+1240x+%2B+44000+
