# Chapter 2, Functions - Chapter 2 Review - Exercises: 62

$f(x)=\frac{1}{2}x-1$

#### Work Step by Step

A linear function has the form $f(x)=ax+b$, with $a=$slope and $b=$y-intercept. Since the slope is $\frac{1}{2}$, $a=\frac{1}{2}$. Since the y-intercept is -1, $b=-1$. Thus the function is: $f(x)=\frac{1}{2}x-1$
