I don't understand what the function would be for the following function table:
When X is 1/Y=45
When X is 2/Y=40
When X is 3/Y=35
When X is 4/Y=30
When X is 5/Y=25
etc.
So what would the function be? I can't get it. Thanks

Yes..thanks. I did that, but now I'm stuck, for some reason, on how to write what the rule for the function would be.
The question asked:
A freezer's temperature is decreasing at a rate of 5 degrees per hour. When the temperature was first measured, it was 50 degrees.
Make a T chart to show the x/y values for all hours shown. (which I did). Then write a linear function that describes the relationship between the temp. and the time. That's the part I'm stuck on. Can you help me with this part? 
y=505x
x(1)=505(1)=45
x(2)=505(2)=40
try doing the rest
