The slope is -30 because she loses $30 each week. This will visually show a line sloping downwards as you read it from left to right.

Shelly has $250 in her savings account. She spends $30 per week. Describe the slope in this situation.
------
balance = -30x + 250
---
slope = -30
----
Note: slope is ALWAYS the amount y changes when x changes by 1.
slope = (change in y)/(change in x) = (change in y) /1 = change in y
