For tax purposes, you may have to report the value of your assets, such as cars or refrigerators. The value you report drops with time. "Straight-line depreciation" assumes that the value is a linear function of time. If a $1020 refrigerator depreciates completely in seven years, find a formula for its value as a function of time. (Let x represent the time in years and y be in terms of dollars.)
I thought it'd be y= -1020/7 +1020 but I was told that I was wrong. Please help me figure this question out!

I posted this question yesterday and I was told I was correct but for some reason the online hw website will not take it.
If you entered it the way you typed it above, I noticed you left out the variable for time
it should be y = -1020/7 x + 1020
or try : y = (-1020/7)x + 1020
checking,
for now, x = 0, x = 0 + 1020 = 1020, checks!
for 7 years from now,
x = 7
y = (-1020/7)(7) + 1020 = 0 , checks!
it should be y = -1020/7 x + 1020
or try : y = (-1020/7)x + 1020
checking,
for now, x = 0, x = 0 + 1020 = 1020, checks!
for 7 years from now,
x = 7
y = (-1020/7)(7) + 1020 = 0 , checks!
Thank you so much! That worked!
