To graph the inequality , start by plotting the boundary line . This line has a slope of 3 and a y-intercept at . Then, because it’s a ‘less than or equal to’ inequality, shade the region below the line, including the line itself. Any point within this shaded area satisfies the inequality!

When solving inequalities, a common mistake is forgetting to flip the inequality sign when multiplying or dividing by a negative number. Remember: if you multiply or divide both sides by a negative value, you must reverse the direction of the inequality to keep it true!
