Question

Find the slope of the linear function f with f(2) = 16 and f(4) = -2

Answer 1

f(2) = 16, Let this be represented as (2, 16)

f(4) = -2, Let this be represented as (4, -2)

`\begin{gathered} \text{slope =}\frac{change\text{ in y}}{\text{change in x}} \\ \\ \text{slope = }(-2-16)/(4-2) \\ \text{slope = }(-18)/(2) \\ \\ \text{slope}=\text{ -9} \end{gathered}`
