help..I know one of the answer choices is A what about C? Check out attachment in the comment box
for choice B: what is 3*4 - 4 ? is -5 less than that number ?
yes! @phi
so it's A&B?
yes, so far. what I did was replace x with the first number in the pair and replace y with the 2nd number. for choice C: (4,-8) in y ≤ 3x -4 replace x with 4: 3*4-4 is -8 less than this number ?
3*4=12-4=8 no! its not less!
-8 is less than 8 (negative numbers are less than positive numbers)
(just like -8 is colder than +8 degrees out)
oh yes I was saying (8) isn't less than -8 because -8 is a negative number but basically it is A&B!
for choice C: (4,-8) in y ≤ 3x -4 we (after simplifying) get -8 ≤ 8 ? and the answer is yes, -8 is less than 8 so choice C is also one of the answers.
just like in choice B: (4,-5) we get - 5 ≤ 8 which is true, so B is one of the answers
thank you so much
now choice D: (0,0) y ≤ 3x-4 replace y with 0, and x with 0: 0 ≤ 3*0 -4 ? 0 ≤ -4 ? is this true?
If this is not clear, take a look at this http://www.khanacademy.org/math/arithmetic/absolute-value/add-sub-negatives/v/negative-numbers-introduction
the correct answers were actually A B C E F
