Question

Ryan uses the rule "add 3" to make a number pattern. John uses the rule "subtract 1" to make a number pattern. They are using their patterns to make ordered pairs (x, y), where Ryan's number represents the x value and John's number represents the y value.

Both boys start their patterns at 8. The ordered pair (8, 8) is shown on the graph.

What are the next three points that follow (8, 8), using Ryan and John's patterns? Plot the points on the coordinate grid.

IMPORTANT: You must graph just the next three points. Any other graphed points will cause all points to be scored as incorrect.

Answer 1

Answer:

x: add 3

y: subtract 1

coordinates are: (8, 8), (11,7), (14,6), (17,5)

Step-by-step explanation:

x: add 3

y: subtract 1

x is formed by adding 3 every time

>> 8, 11, 14, 17, ...

y is formed by subtracting 1 every time

>> 8, 7, 6, 5, ...

Hope that helps!!
