What is the relationship between the ratios? 4.8/7.2 and 0.06/0.09

The ratios are

Proportional or Non-Proportional?

the answer is non proportional

Non-proportional! And I know that someone has already answered but I just wanted to answer too. Okay, if I don't stop typing things will get... awkward.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
