Scientists are studying the temperature on a distant planet. Let $y$ represent the temperature $($in degrees Celsius$).$ Let $x$ represent the height above the surface $($in kilometers$).$ Suppose that $x$ and $y$ are related by the equation $y=36-7x.$

Answer the questions below.

Note that a change can be an increase or a decrease.

For an increase, use a positive number. For a decrease, use a negative number.

What is the temperature change for each kilometer we go up from the surface?

$C$

What is the temperature on the surface of the planet?

$C$
