A scatter plot is shown:
MatroZZZ [7]

Answer:

The correct option is 2.

Step-by-step explanation:

From the given graph it is noticed that the data points are located at (0,0), (1,0.25), (2,1), (3,2), (4,3), (5,4), (5.5,5), (6,6), (6.4,7), (6.7,7.8) and (7,9).

The rate of change from first two data points is

m_1=\frac{y_2-y_1}{x_2-x_1}=\frac{0.25-0}{1-0}=0.25

The rate of change from next two data points is

m_2=\frac{2-1}{3-2}=1

m_1\neq m_2

The rate of change it not constant, therefore the given data points are non linear.

The value of y increases as the value of x-increases. It means there is a positive relation between x and y.

Therefore the graph represent a Nonlinear positive association between x and y. Option 2 is correct.

An electrician charges a set fee of $100 for every house call and then charges an additional hourly rate. One day, the electrici
DIA [1.3K]

Answer:

C=75t+100

Step-by-step explanation:

Let

C(t) ---->the total cost of the electrician's services in dollars

t ---> the number of hours

we know that

The linear function in slope intercept form is equal to

C=mt+b

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

the y-intercept is equal to

b=\$100 ----> set fee

we have the ordered pair (2,250)

substitute the given values

250=m(2)+100

Solve for m

2m=250-100

2m=150

m=\$75\ per\ hour

The linear function is equal to

C=75t+100
