i. Show that the general linear equation ax+by = c with b≠0 can be written as which is the equation of a line in slope-intercept form.

ii. Show that the general linear equation ax+by = c with b = 0 but a ≠ 0 can be written as , which is the equation of a vertical line. [Note: Since these steps are reversible, parts (i) and (ii) together show that the general linear equation ax+by = c (for a and b not both zero) includes vertical and nonvertical lines.]
