Question 175962
Are the following two graphs in a family? If so,explain why. y=-2x+3 and y= 2x+3
------------------
y = -2x + 3
y is your investment value in millions of dollars
The slope is -2 so you expect to lose 2 million each of the next few years.
----------------
y = 2x+3
Your home expenses are currently 3000/month; you expect them to 
rise 2000 each of the next few months.
