Answer:

y = 3x -18 (i added a graph)

Step-by-step explanation:

in order to find the slope you could do y2-y1/x2-x1

-6/4 - 3/7

-9/-3 = 3

and if you want to find the y-intercept:

-6 - 3 = -9

4 - 1 =  3

(3,-9)

-9 - 3 = -12

3 - 1 = 2

(2,-12)

-12 - 3 = -15

2 - 1 = 1

(1,-15)

-15 - 3 = -18

1 - 1 = 0

(0,-18)

therefore, the y-intercept is -18

In a recent year, the population of California was about 2.52 x 10^7 people. Its land area is about 4.05 x 10^5 km^2. What was t
andrezito [222]

The population of California = 2.52 \times 10^7 people.

Land area of California = 4.05 \times 10^5km^2.

We have to determine the average number of people per square kilometer.

Average number of people per square kilometer =

Land area of California \div Population of California

= 4.05 \times 10^5 \div 2.52 \times 10^7

= 1.6 \times 10^{-2}

Therefore, the average number of people per square kilometer is  1.6 \times 10^{-2}.

It is represented in scientific notation as Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

Replacing terms:

\text{Area}_{\text{label}}=2\pi\cdot1.5\cdot4=12\pi=37.7in^2
