-- Slope:
   Every time you add a topping, the cost increases by $2.
   So the slope is $2 per topping.

           C = 2t  so far

-- But that can't be the whole equation.
   If it were the whole equation, then the cost of a pizza
   with no toppings would be zero.
   The cost of a pizza with no toppings is actually $8 ,
   so the whole equation is

              C  =  2t + 8 .
