3. Graph the following inequality using a number line.

To graph an inequality on a number line, first identify the type of inequality symbol you're dealing with: for example, if it's "<" or ">", you'll use an open circle to indicate that the endpoint is not included. If it's "≤" or "≥", use a closed circle to show that it is included. Next, shade the line in the direction that represents all the values that satisfy the inequality. For example, for "x > 3," place an open circle on 3 and shade to the right. Inequalities like this aren't just a math concept; they’re widely useful in real-life situations! For instance, if you’re budgeting your monthly expenses, you might create inequalities to represent how much you can spend on various categories without exceeding your total budget. By understanding how to visualize these limits on a number line, you can make informed financial decisions with ease!
