The function f(x) is shown in the graph.

what is the equation for f(x)?

enter your answer in the box.

f(x)= [ ]

Answer

f(x) =  (5/-6)x - 1

Explanation

The first step is to calculate the slope of the graph.

Slope = (change in y) / (change in x)

         = (4 - -1)/(-6 - 0)

         = 5/-6

Using a point (0, -1) and a general point (x, y)

slope = 5/-6

(y - -1)/(x - 0) = 5/-6

(y + 1)/x = 5/-6

y + 1 = (5/-6)x

y = (5/-6)x - 1

∴ f(x) =  (5/-6)x - 1
