Chapter 1.2, Problem 2ED

(A) Graph $y=x+b$ for $b=-5,-3,0,3$ and $5$ simultaneously in the same coordinate

system. Verbally describe the geometric significance of $b.$

(B) Graph $y=mx-1$ for $m=-2,-1,0,1,$ and $2$ simultaneously in the same coordinate

system. Verbally describe the geometric significance of $m.$

(C) Using a graphing calculator, explore the graph of $y=mx+b$ for different values of $m$

and $b.$
