Closed number line. The circles indicate the limits of the inequality -1 and 10. For and use a closed dot to indicate the number itself is part of the solution. The number line should now be divided into 2 regions -- one to the left of the point and one to the right of the point Next pick a point in each region and test it -- see if it satisfies the inequality when plugged in for the variable.
