Giselle pays $190 in advance on her account at the athletic club. Each time she uses the club, $10 is deducted from the account. Model the situation with a linear function.
In using a linear function, follow the pattern y=mx + b. In this scenario, the m (which represents slope) is -10 since $10 is taken away every time. The b(which represents y-int) is 190 because you start with 190 (x=0)
