4. Pizza costs $1.50 per slice. Use a table and an equation to represent the relationship between the number of slices of pizza bought and the total cost.

5. Give an example of an open equation


6. How can you use an equation to make a prediction from a pattern?


1. Yes
2. No
3. ( 4, 0) and ( 3, -1)
4. y=1.50x; y=total number of slices x= the amount of slices 1.50=the cost of one slice

5 and 6 I need help with

Answer 1

Well, an algebraic open equation (also known as an open sentence) is a mathematical equation that is neither true nor false. so an example of an open equation could be x + 3 = 7 or 2x = 12. Hope this helps with #5 :D
