# Graphing linear equations and applications

The number of arrests y of a city over a period of time x is graphed on a rectangular coordinate system. Write a paragraph describing your interpretation when the slope is positive, zero, and negative. If you were buying a home in this particular city, which slope would be most attractive to you and why?

#### Solution Preview

The slope of a line is defined as the change in y divided by the corresponding change in x: m=(y1-y0)/(x1-x0)

If the x-axis corresponds to time, and the y-axis holds the number of arrests at a ...
