The relationship between x and y is that y is just x+3.5. So if x is 13, then y is 13+3.5 which is 16.5.
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Let
y ----> the total amount of savings
x ----> the number of months
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
<em>Herman</em>
The slope is equal to 
The y-intercept is 
substitute
----> equation A
<em>Jackie</em>
The slope is equal to 
The y-intercept is 
substitute
----> equation B
Part 1) In how many months will they have the same amount of savings?
equate equation A and equation B

solve for x



Part 2) How much will each of them have saved?
substitute the value of x=10 months in any of the equations
equation A

equation B
