Please let me know if you need any clarification. I'm always happy to answer your questions.

a) let number of months be x.

x=500/75; 75x=500; 0=500-75x in standard form the equation will be of the form f(x)=mx+c

equation is f(x)=500-75x

b) variable x is the number of months Barry has paid his dad while f(x) is the balance Barry owe his dad at a particular month x.

c) x      1         2      3

    f(x)   425    350   275

d) y-intersept is 500 and x-intersept is 0=500-75x; x-intersept= 6.66667

y-intersept means that before any payments Barry made, he owe his dad $500, x-intersept indicates that Barry cleared his debt after 6.66667 months

after 4 months Barry owe his father 500-75(4)=500-300= $200
