Geometry; 5/10

We continued working with line equations today, but without graphing them.  We introduced a new type of line equation:  the point-slope form of a line.  We went over several examples of how to work with this equation and convert it to the other forms of lines that we have studied before.  The students then got started on their assignment towards the last part of the period.

Assignment:  section 13-7;  page 555;  WE  #1-28 all;     answer #1-25 in the y = mx + b form;  answer #26-28 in the standard form;  Ax + By = C
