Question

Part A

Which inequality represents the solution set?
a x < −2
b x > −2
c x < 1.2
d x > 1.2

Part B

Graph the solution set of the inequality.
a A number line from negative 8 to 8. There is an open dot at negative 2 and the number line is shaded to the left of the dot.
b A number line from negative 8 to 8. There is a filled-in dot at negative 2 and the number line is shaded to the right of the dot.
c A number line from negative 8 to 8. There is an open dot at 2 and the number line is shaded to the right of the dot.
d A number line from negative 8 to 8. There is a filled-in dot at 2 and the number line is shaded to the left of the dot.

Answer 1

Part A: a x < −2

Part B: a A number line from negative 8 to 8. There is an open dot at negative 2 and the number line is shaded to the left of the dot.
