Question 428167
<font face="Times New Roman" size="+2">


Yes, your answer is correct.  In order to get rid of the minus sign in the y term, you had to multiply by a negative number (*[tex \Large -\frac{1}{4}] in this case) so you had to reverse the sense of the inequality, changing from less than to greater than.


Here's how to remind yourself that this makes sense:


2  is certainly less than 3, that is *[tex \Large 2\ <\ 3]


Now multiply both sides by -1:  *[tex \Large -2\ <^?\ -3]


Nope, not less than any more -- minus 2 is GREATER than minus 3:  *[tex \Large -2\ >\ -3]

My calculator said it, I believe it, that settles it
