Let g be the number of grandchildren, and d be the number of dogs. They both have only one head, so the number of heads is
Grandchildren have 2 legs, while dogs have 4. So, the total number of legs is
From the first equation (the one for the heads) we can derive
Substitute this into the second to get
So, there are 9 dogs and (from the first equation
We know that
An ordered pair is used to locate a point on a coordinate grid.
The first number in an ordered pair is the x-coordinate, and the second number in an ordered pair is the y-coordinate.
In this problem, the ordered pair is
so
the x-coordinate is equal to
the y-coordinate is equal to
therefore
Rule N 1
The y-value is times the x-value
Rule N 2
The y-value is greater than the x-value
Both are possible because their solutions include the ordered pair listed
