The development of cities around urban centers was a gradual process rather than a well-defined event. Cities and villages & towns differ in two ways. First, cities were larger and more complex. Professional craft workers refined existing technologies, invented new ones, and raised levels of quality and production. Second, Neolithic villages & towns served the needs of their inhabitants and immediate neighbors, whereas cities decisively influenced the political, economic,and cultural life of large regions.

Answer:
D. y = 1/2x + 3/2
Explanation:
You probably already know the point slope equation:
y = m(x - x₀) + y₀
All you need is the slope and the (x₀, y₀).
The (x₀, y₀) could be solved by plugging in the given x=-1 value into the function.
m, the slope, is the same as a derivative; ie. a derivative is a slope.
So solve for the derivative and find the slope at x=-1.
Plug into point slope equation and simplify.
