Let us learn how to graph inequalities on a number line. We can graph inequalities on a number line by marking the part that the inequality represents. Inequality is a mathematical statement used for the comparison of quantities. So, if you have chosen 1 as the scale, then mark 0, 1, 2, 3, 4, and so on. Step 3: Mark the points at equal intervals.(Determining an appropriate scale depends on the factors of the given number) If you have to plot 50, you can choose a scale of either 5, 10, or 25. For example, if you have to plot 5, then you can choose a scale of 1. Step 2: Choose a scale depending on the given number.(You can also draw a vertical number line) Step 1: Draw a horizontal line with arrows on both ends.In order to draw a number line or to plot a number on it, we use the following steps. Observe the horizontal number line given below. For example, 3 comes to the right of 1, so 3 > 1. This means that the numbers present on the right are larger than the numbers on the left. So, we can say that on a number line, as we move towards the right, the value of numbers increases. The numbers to the left of 0 are negative numbers and the numbers to the right of 0 are all positive numbers. Zero (0) is considered to be the origin of a number line. Writing down numbers on a number line makes it easy for us to compare them and to perform basic arithmetic operations on them. A visual representation of numbers on a straight line drawn either horizontally or vertically is known as a number line.
