    one 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: y-x < -3 ? 2 - 6 < -3 is this true? is 2-6 less than -3 ?

    2-6 is -4 -4 is less than -3 (maybe that is confusing ?)

    so 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 y-x < -3 ? 6-2 < -3 ? 4 < -3 No way! this is not true

    you could use algebra to rewrite the equation to (for example) y-x < -3 y < x-3 (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 < 6-3 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.
