Question

The temperature in a freezer is falling steadily at a rate of two degrees Fahrenheit per minute. The function y equals twenty-five minus two x gives the temperature y after x minutes. Which set of terms best describes the function y equals twenty-five minus two x in this scenario?

Answer 4

y equals twenty-five minus two x gives the temperature y after x minutes.

It is easier to read if you write it like this
y = 25 - 2x

you can also write it
y = -2 x + 25

does that equation remind you of y= mx + b ???

Answer 5

Yes it does.

Answer 6

what kind of equation is it ? (Please say, it is the equation of a line)

Answer 7

which means LINEAR

discrete means the answers are specific numbers, like 1,2,3, with gaps
continuous means y can be any number (continuous... no gaps... like a line)

Answer 8
