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.

y=-2x+3
y= 2x+3
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+-2x+%2B3%2C+2x+%2B3%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions -2x +3 and 2x +3).
These 2 lines are perpendicular because the slopes are negative recipricals of the other.
