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=50-5x

x(1)=50-5(1)=45

x(2)=50-5(2)=40

try doing the rest
