A copier was purchased for $7800. For tax purposes the machine depreciates at $1300 per year. If X represents the number of years after the purchase, then the value of the copier y after X years is given by the equation Y equals 7800-1300 X. Find the XNY intercepts and explain the significance in each intercept. Also find the value of the copier after three years

Me. i can't figure out this question. give an explanation too. .
