Remember that x = 3 tells you that the line will intersect with the x-axis at positive 3, just as y = -4 will intersect with the y-axis at negative 4. That's the whole key to determining both how to identify what kind of line it will be, and in graphing them correctly.
Homework #72: TB pg 249 (#19-26 all; identify and graph each) & TB pg 574 (#1-11 odd)
Be sure to check your answers in the back of the book when finished!
