There are infinitely many equations of lines of the form but there are
specific ones where a, band care consecutive integers. this is called a family of lines
where the coefficients a, band care related in some way. the family of lines where a, b,
and c are consecutive integers is an interesting group of lines. list at least 5 different lines
in this family (both positive and negative coefficients) and graph them on your graph
paper. what do you notice or wonder? write down some conjectures and come to class
with an argument why your conjecture might be true.
