The answer to your question is,
Each time they assume the sum is rational; however, upon rearranging the terms of their equation, they get a contradiction (that an irrational number is equal to a rational number). Since the assumption that the sum of a rational and irrational number is rational leads to a contradiction, the sum must be irrational.

Let
x--------> the number of weeks
f(x)------->Peter's total video game time in hours
we know that
<u>The domain</u> of the function is the interval [0, 8]
<u>The y-intercept</u> of the function is the point (0,10)
is the initial amount of hours Peter's played
<u>The slope of the function</u> is equal to 
Is the rate at how many hours he is playing extra each week
