8.  Explain the relationship between the graphical representation of intercepts (where they cross each axis) and the algebraic representation of intercepts (where one of the variables is zero).

Graph each of these linear equations in the method you prefer.  You may use a table of values with patterns like we did in Section I-2, or you may choose just to find the intercepts.  Some equations might be arranged in such a way that one method might be easier than another method.

9.  x + 2y = 6       10.  -2x – 3y=12      11.  2x = 4y – 5     12.  -x = 3y – 2       13.  (0.5)y = x – 2
