Linear graph

[r.am...@hotmail.com]

Hi!

I am writing an economical assignment and i'm puzzled by the design of my graph.

It's a normal linear equation: 20,000,000 - 4,000,000x.

When i plot it in my graph the line gets drawn as a straight vertical line with a 90 degrees angle on the x-axis.

I've been zooming out to large values and there's still no bending of the line.

Can you help me?
