when you're graphing inequalities with the >< and the >< or equal to signs.
does it flip with a negative number followed by x? because a negative x a negative is a positive, flipping lets say... x > 2 and it flips to x < 2
when does it flip? ... im behind on my review due tomorrow... im kinda cooked ngl.

You flip the inequality sign only when you multiply or divide both sides by a negative number.ᴛʜᴇ ᴍᴏᴏɴ ᴜɴᴅᴇʀꜱᴛᴀɴᴅꜱ ᴡʜᴀᴛ ɪᴛ ᴍᴇᴀɴꜱ ᴛᴏ ʙᴇ ʜᴜᴍᴀɴ, ᴜɴᴄᴇʀᴛᴀɪɴ, ᴀʟᴏɴᴇ, ᴄʀᴀᴛᴇʀᴇᴅ.

You flip the inequality sign only when you multiply or divide both sides by a negative number.
Think of a simple true statement: (2 < 5) (2 is less than 5).
If you multiply both sides by (-1), the numbers become (-2) and (-5).
On a number line, (-2) is further to the right than (-5), meaning (-2) is actually greater than (-5).
To keep the statement true, you must flip the sign: (-2 > -5).
