How do you determine whether a relationship represented as as graph is linear or nonlinear

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

Solve the following inequalities and show the solution on a number line. 3/4 (2x-7) ≤ 5
