2. Let A = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} and suppose R is a relation defined by a is related to b if a divides b. You must show that the property holds or give a counterexample. a) Write out the ordered pairs that make up the set R. b) Is R reflexive, irreflexive, or neither? d) Is R transitive? c) Is R symmetric, antisymmetric, or neither? e) Draw a graph of R.

Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
