Lesson 4: Topic E & F: Foundations

# Interpreting relationships in ordered pairs

Explore the concept of numerical patterns, focusing on how to generate, identify, and graph these patterns on a coordinate plane. Understand the relationships between corresponding terms in two different patterns and how these relationships can be represented as ordered pairs. Created by Sal Khan.

• What is a constant?
• A constant is a specific number. In the expression 2x+6, the 6 is a constant. It will not change. The 2 is the coefficient of the variable X. Since the value of X can change, the value of 2X will also change accordingly. This is why we don't typically call the 2 a constant.
Hope this helps.
• what are coordinate graphs
• Why is pattern A the horizontal axis while pattern B is your vertical axis. Pretty sure somebody already asked this but I forget so...
• It is because thats the way its graphed.
• Whats a constant number?
• Its a number that constantly stays the same.
• I need a better understanding.
• I have a question. If you have numbers 0, 3,and 9 and need y for each greater by 0.75, how do you solve?
• 0.75 is the fraction equivalent of 3/4.
If you add 3/4 to 0, it becomes 3/4, and its decimal equivalent remains 0.75
If you add 3/4 to 3, it becomes 3 3/4, or 15/4. Its decimal equivalent is 3.75
If you add 3/4 to 9, it becomes 9 3/4, or 39/4. Its decimal equivalent is 9.75
I hope that this was helpful! :)
• Why do we need the axes for the example?
• ' 'I get it, Its just that some of the problems are just very confusing.. I don't know why..' '
