Is the relationship in the table linear, exponential, or neither? explain how you know.

write an equation relating the amount saved(s) in dollars to time (t) in weeks.

explain what the slope and y-intercept mean in this problem situation.

A- It's LINEAR: every 2 other weeks, her savings increase by a CONSTANT amount of $12 (per 2 weeks) or $6/week

B- After the 2 first week she had $20 less the $12 (baby sitting for 2 weeks) =$8. This is the amount she saved prior to babysitting , then each week she added $6 (or $12 in 2 weeks)
If Y is the total amount of saving after a period of time T  & $6 is the rate per week & she started with $8, then the equation becomes Y= 6 T +8, where T is the number of weeks

C- the slope is the coefficient of T that means 6
As for Y intercept or where the function intercepts the Y axis it happens for T=0 & in this case Y intercept = 8
Hope it's clear
