Analyze Table: Look at the table, for each increase of 1 bagel, the coffees increase by 1. So, it's like adding 1 coffee for each extra bagel.
Establish Starting Point: If we start at 7 bagels and 2 coffees, when we got 8 bagels we got 3 coffees. So, if b=7, then c=2. We can use this as our starting point.
Find Difference: Now, let's find the difference between the bagels and coffees. If we take the bagels and subtract 5, we should get the coffees. Like, 7−5=2, 8−5=3, and so on.
Verify Equation: So the equation is c=b−5. This should work for all the pairs in the table. Let's check it real quick, plug in b=10, we should get c=5. Yup, 10−5=5, it works!
