How do you graph -2x5 on a number line?

If your solution comes from an equation, then you simply plot your answer on the number line. If the solution comes from an inequality, you either circle the solution, or color it in, depending on whether your inequality was < or < =. If it is <, then circle your point on the number line, and shade the line for numbers less than your solution. If it is >, circle your point on the number line, and shade the line for the numbers greater than your solution. If it is <=, repeat above, but instead of circling, shade your solution's point as well.
