Points (x,y); (x)Altitude, (y)Temperature to boil

Described points are (0, 100) and (7, 75.5).
Determine the equation (linear) from those two points.

You are given the points:
( 0, 100 )
( 7, 75.5 )
Use the general point-slope formula

---------------------------
check:
( 0,100 )

and
( 7, 75.5 )

OK
