In order to graph an equation on a number line, the following are needed:
- Add or subtract on both sides of the inequality to isolate the variable.
- Multiply or divide on both sides to completely isolate the variable.
- If the variable is negative, multiply by minus one on both sides and change the orientation of the sign. If it is greater than, change to less than.
<h3>What is an inequality?</h3>
Inequality is an algebraic expression where the variable and numerical terms separated by inequality symbols, greater than, greater than, greater than or equal to, less than, less than or equal to.
The general equation of a straight line is y = mx + c. The equation of a straight line with gradient m and intercept c on the y-axis is y = mx + c.
