find the equation of a secant line containing the given points (1,f(1) and (2,f(2))

**Reiny**, Friday, November 2, 2012 at 5:30pmf(1) = 4

f(2) = 14

rate of change = (14-4)/(2-1) = 10

the slope of the secant is 10, (see above)

equation is y = 10x + b

but (1,4) lies on it, so

4 = 10(1) + b

b = -6

secant equation: y = 10x - 6
