Help me please

oh boi this is gonna take a long time to type. hang in there.

Step-by-step explanation:

#1: S. A rule is used to find the age of Cassandra's mother no matter the age of Cassandra. Therefore, the answer to #1 is 2C + 9 = M where C is equal to the age of Cassandra.

#2: The rule 2C + 9 = M relates to this because the variale C represents Cassandra's age, the +9 represents her age plus nine is her Mother's age, the 2 in front of the variable C represents the doubling of Cassandra's age, and M represents her mother's age.  

#3: The rule IS the process that each student used to find her mother's age. This is how they are both related (the process and the rule).

#4: This is all you because I'm pretty sure this is from another problem you did or something.

#5: For a and b, try to find what x (the input) is done to ... to get y (the output). Look for patterns between the two numbers and look for a RULE that can be used for all. The number 0 is the most important when looking for the rule. :)

OH! MAKE SURE TO PUT THIS INTO YOUR OWN WORDS! (maybe you and i have a different way of speaking and this might get SUS)

answer: i think it is (1,-2)
