A number that is shown plotted on the number line include the following: A. -2 1/4.
In Mathematics and Geometry, a number line is a type of graph that is composed of a graduated straight line, which typically comprises both negative and positive numerical values that are located at equal intervals along its length.
This ultimately implies that, every number line would primarily increase in numerical value towards the right from 0 and decrease in numerical value towards the left from 0.
Note: Each of the interval on this number line represents 1 unit.
Since the solid circle was placed to the left of 0 and immediately after -2, it implies that only the number -2 1/4 represents the number that is shown plotted on the number line.
