If you are multiplying or dividing by a _______________ you always switch the inequality.

• less than

• n< -1

• negative

• no

that is underlined stands for

• greater than or equal to

• less than or equal to

If the inequality is -8 < X which way do you draw the arrow on the number line?

• negative

• coefficient (when you multiply or divide by a negative number you must switch the direction of the equality)

• open circle at - 8 and then shade towards the larger numbers (right)

• No
