Question

The city of Phoenix, Arizona, has laid out their main city streets in a linear grid. Roads run north to south or east to west. Finding intersections of the streets is pretty easy, since every road is a straight line. Imagine if Phoenix has used only curved roads, or circular roads, or roads that bent and went off in different directions. Thinking of those roads in Phoenix as linear equations, we will now solve systems that have non-linear equations in them using graphs. These graphs will serve as your GPS to find the intersections of the “roads.”

Can you put the analogy (first paragraph) in your own words and explain to me?

Answer 8

I would if i myself understood. I have no clue what they are asking me to do...

Answer 9

Have you read the first paragraph?

Answer 10

yes. Ive read the whole thing multiple times and still dont understand.... I'm horrible at math.

d. non-linear equations

Answer 12

I dont know what they mean... i know its sad...

Its okay... Thank for responding. No one else is really helping me....

Answer 19

Maybe @hartnn can help?

Answer 20

Hopefully! That'd be great.

Answer 21

@hartnn could you help me?

Answer 22

I'll only have time to make a brief description before I have to go.
The first paragraph means that the city in plan represents a Cartesian plane with its x- and y coordinates. The streets represents lines, or linear functions in the plane.
When the streets are straight, they represent linear functions, or first-degree functions.
When the streets are curved, they represent non-linear functions.
The intersections of streets are the solutions to systems of 2 linear equations.
The intersections of curved streets are the solutions of systems of non-linear equations.
So the aerial view of a city resembles very much the Cartesian plane in mathematics.
