The solution is a two-step process:

1). Draw the graph of the function. On a piece of graph paper, draw a set of

x/y axes. Then with your pencil, make a dot on the y-axis where y=100, and

another dot on the x-axis where x=12.5 . Now place your ruler against the

two dots, and taking hold of your pencil again, connect the two dots, and

extend the line as far as you can in both directions. Technically, it goes on

forever in both directions, and never ends.

Now you're ready to solve the equation.

2). Every point on the line you drew is a pair of numbers ... 'x' and 'y' ... that is

a solution to the equation. How many are there ? Don't try to list them, as the

list is infinite. That's what's so great about the graph ... it shows an enormous

number of solutions with one simple picture.
