Best ResponseYou've already chosen the best response.2one way, is replace the x and y with numbers and do the arithmetic test (6,2) which means x=6 and y=2 replace x with 6 and y with 2 in your relation: yx < 3 ? 2  6 < 3 is this true? is 26 less than 3 ?

Best ResponseYou've already chosen the best response.2so the first choice is the answer. we could test the others, and find that they do not work. example: test (2,6) x is 2 and y is 6 yx < 3 ? 62 < 3 ? 4 < 3 No way! this is not true

Best ResponseYou've already chosen the best response.2you could use algebra to rewrite the equation to (for example) yx < 3 y < x3 (add +x to both sides) this is the same relation, written differently. *maybe* this is easier to test ? test (6,2) : x is 6, y is 2 2 < 63 2 < 3 yes this is true. it gives the correct answer, and we did not get negative numbers, so maybe it is less confusing.... but I would just use the original form and practice understanding negative numbers.
