Question

Alyssa opens a savings account with $7. She saves $2 each week. The table represents her account balance. Decide whether the table represents a linear function or a nonlinear function. Alyssa's Savings Account Week 01 2 3 4 5 Money in 7 9 Account 11 13 15 17 The table represents a function. liner nonlinear

Answer 1

We are given a chart with two variables, we can notice that variable "week" changes by one, that is:

$0,1,2,3,4,5$

And for every change by 1 in the variable "week" we notice that the variable "money in account" changes by 2, that is:

$7,9,11,13,15,17$

Therefore, since for every constant change in one variable we have a constant change in the other, this means that the relationship is linear.
