A bank charges you $3 each time you use an out of network Atm. At the beginning of the month you have $1500 in your bank account. You withdraw $60 from your bank account each time you use an out of network ATM. Write and graph a linear equation that represents the balance in your account after you use an out of network Atm x times.

For this you would use the normal y=mx+b formula. You have a total of 1500 dollars in your account so that would be your constant or your b. Your m or your slope is rise over run. To find this you would add what is taken out each time, so you would add 60 and 3 and that would be your rise y to get 63. Your run would be the number of times or x and that is one inbetween each time. Put those together to get 63/1 and make it negative because it is subtracting that amount each time making m be -63/1. that makes your equation y=-63/1x+1500. Do you need me to explain the graphing for that?
