Question

How do you show where an inequality is true on a number line? 100 points!

Answer 1

To plot an inequality, such as x>3, on a number line, first draw a circle over the number (e.g., 3).
Then if the sign includes equal to (≥ or ≤), fill in the circle.
If the sign does not include equal to (> or <), leave the circle unfilled in.

Hope this helped!

Answer 2

Rearrange the equation so "y" is on the left and everything else on the right.
Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
Shade above the line for a "greater than" (y> or y≥)
or below the line for a "less than" (y< or y≤).
