<PRE><B>Question 267616</B>
f is a linear function. 

If f(2) = 10 
   f(10) = -2
------------------
slope = (10--2)/(2-10) = 12/-8 = -3/2
--------------
Form: y = mx + b
You know m = -3/2 and y = 10 when x = 2.
Solve for &quot;b&quot;:
10 = (-3/2)2 + b
b = 13
-----------------
Equation:
f(x) = (-3/2)x + 13
-----------------------

find f(-10) = (-3/2)(-10) + 13 = 28 
and f(100) = (-3/2)(100) + 13 = -150 + 13 = -137
