Question 1136038
<br>
The m-intercept is the value of m (number of months) when D (her debt) becomes 0.<br>
0 = -100m+5900
100m = 5900
m = 59<br>
Her credit card debt will be paid off after 59 months.<br>
More precisely, since the problem says -100m+5900 is an ESTIMATE of her credit card debt, her credit card debt will be paid off in ABOUT 59 months.
