Y = -2x + 5
All you have to do when coming across this type of problem is substitute x and y for the points given, as well as change whatever b is, in this case 5, for b. For example: -3 = -2(4) + b
So Jose already gave 2 out of 67 cents of change to the customer, or:
67-2 - 65.
Nickels are worth 5 cents each, so all you gotta do now is divide 65 by 5 to get the number of nickels Jose still needs to give:
65/5 = 13
Jose needs to give the customer 13 nickels to provide the correct amount of change :)
