In each of parts (a) through (d), first solve the equation for y so that you can enter it in your graphing utility. Then use the graphing utility to graph the equation in an appropriate viewing rectangle. In each case, the graph is a line. Given that the x- and y-intercepts are (in every case here) integers, read their values off the screen and write them down for easy reference when you get to part (e).

(a)

(b)

(c)

(d)

(e) On the basis of your results in parts (a) through (d), describe, in general, the graph of the equation , where a and b are nonzero constants.
