a real-life situation where a straight-line graph might be applicable and explain why you think this might be true.
Think about a real-life situation that follows a linear equation, with the independent variable being years. What would the slope tell you about future years? Please Help!!!

Global coordinates? No, that would use a polar grid. But if you're using a rectangular projection, then it is very useful in trying to plot distances and stuff like that.

How about the speed of a glacier? It moves so slowly that measuring the time in hours or days doesn't really tell you much. The slope of the line represents the speed, and by projecting it onto future years, it tells you where the glacier will be in a year, a decade, or even a century. Problems like these form the foundation for a branch of mathematics called differential calculus, which also deals with non-linear graphs. Beware. :p

You could graph the distance from the origin of the Big Bang to the initial light (or EM waves) that was (were) produced with respect to time of course. Since light travels at a constant velocity (direction and speed) this should be a linear function.
The slope would tell you where the light would be in future years.

Is this one question or two?
