Mike is saving money earned from a job. For every $20 Mike earns, he puts $4 into savings. Mike is going to graph his savings. T
madreJ [45]
The first thing we must do for this case is to define the variables:
 x = the amount earned
 y = the money saved
 The equation of the line that adapts to this problem is given by:
 y = (1/5) x
 Let's check:
 For x = 20 $ we have:
 y = (1/5) (20)
 y = 4 $
 Answer:
 The slope of Mike's graphed line will be:
