# Chapter 2 - Section 2.4 - Linear Functions and Slope - Exercise Set: 31

#### Answer

slope = -2 y-intercept = 1 Refer to the image below for the graph.

#### Work Step by Step

RECALL: The slope-intercept form of a line's equation is $y=mx+b$, where $m$=slope and $b$=the y-intercept. The given equation is in slope-intercept form with m=-2 and b=1. Thus, the equation has: slope = -2 y-intercept = 1 To graph this equation, perform the following steps: (1) Create a table of values by assigning different values to $x$ and then solving for the corresponding value of y for each one. (Refer to the attached image below for the table.) (2) Plot each ordered pair, and then connect the points using a straight-edge. (Refer to the attached image in the answer part above for the graph.)
