To determine the correct slope, we need to find the change in y and the change in x.
In this case, the change in y represents the change in the remaining balance (amount in dollars) and the change in x represents the change in months.
Looking at the graph, we can see that for every 1 month, the remaining balance decreases by $175.
So, the correct slope is:
m = change in y / change in x
= -$175 / 1
= -175/1
= -175
Therefore, the correct example that models the correct slope is:
m = -2,625 - 1,400 / 11 - 6
= -1,225 / 5
= -245
