# Chapter 5 - Linear Functions - 5-4 Point-Slope Form - Practice and Problem-Solving Exercises - Page 317: 23

$y = 8.5x$ This line does not have an intercept in the formula, so the intercept is 0. The slope is the hourly wage and that a person would earn 8.50 for each hour they worked. Since the intercept is 0, this means that there no bonus (or guaranteed money) for a worker.

#### Work Step by Step

$m = (25.5-8.5)/(3-1) = 17/2 = 8.5$ $y = mx+b$ $8.5 = 8.5 * 1 +b$ $8.5 = 8.5 + b$ $0 = b$
