When working with one step equations what are the rules to follow?
Make sure you use the opposite operation.
If addition use subtraction.
If subtraction use addition.
If multiplication use division.
If division use multiplication.
Describe the X and Y axis. Use ordered pairs in your examples.
The X axis is horizontal. The Y axis is vertical.
Ordered pair on the X axis (4, 0)
Ordered pair on the Y axis (0, 10)
