can someone please help me with this question?

Given the function f(x)=3x-9

Find the rate of the change between the stated values for x: 7 to 8

A. Find the equation of a secant line containg the given point (7,f,(7)) and (8,f,8))

B. Find the rate of change between the stated values for x: 7 to 8

1 answer

z. f(x)=3x-9

b. rate of change is 3

explaination: find the two points (at x=7, and x=8).

then find the slope (f(8)-f(7)/(1))

then the equation is of the form y=slope*x+b. Put either point in, and solve fodr b.
