Question

I need some help so see if an equation is linear or not f(p)=2/5x-5

Answer 1

`\begin{gathered} f(p)=(2)/(5)x-5\text{ } \\ \text{ This is a linear function.} \end{gathered}`

Explanation:

A linear equation is represented by the following equation in slope-intercept form:

`\begin{gathered} y=mx+b \\ \text{where,} \\ m=\text{slope } \\ b=\text{ y-intercept} \end{gathered}`

Then, if we have this function:

`f(p)=(2)/(5)x-5`

Notice that is the slope-intercept form of a linear equation.
