Graphing Inequality Word Problems Explained

The video tutorial explains how to graph inequality word problems using a real-world example of an elevator's weight limit. It covers setting up the problem, writing the inequality, graphing it, and analyzing the graph to answer additional questions. The tutorial emphasizes understanding the relationship between the inequality and the graph's shaded region.

What is the standard form of an inequality word problem?

• ax + by = c

• ax + by ≤ c

• ax - by = c

• ax - by ≥ c

What is the maximum weight allowed in the elevator?

• 2000 pounds

• 1500 pounds

• 1200 pounds

• 1000 pounds

Would it be safe for 4 males and 4 females to ride the elevator?

• Yes, it is within the weight limit.

• No, it exceeds the weight limit.

• Yes, but only if they are children.

• No, it is exactly at the weight limit.
