The given points are (2, -3) and (2, 9)

The x-component of the two points is the same. Which means the line passing through the given two points is a vertical line and slope of a vertical line is undefined.

You can also validate it using the formula of finding slope.

Slope = (-3-9)/(2-2) = -12/0 = undefined

So, first option is the correct answer.

In 1990 the average family income was about $ 39 , 000 , and in 2010 it was about $ 70 , 768 . Let x = 0 represent 1990, x = 1 r
iren2701 [21]

Answer:

<em />f(x) = 1588.4x + 39000<em />

f(15) = 62826

Step-by-step explanation:

Given

In 1990; Income= $39000

In 2010; Income= $70768

Solving (a): An equation in form of f(x) = ax + b

First, we need to determine the slope, a

a = \frac{y_2 - y_1}{x_2 - x_1}

Taking y as income and x as year index.

When x = 0; y = 39000

When x = 20; y = 70768

Substitute these values in the above formula

a = \frac{70768 - 39000}{20 - 0}

a = \frac{31768}{20}

a = 1588.4

Next, is to determine the formula using:

y - y_1 = a(x - x_1)

<em>Considering :When x = 0; y = 39000, we have</em>

<em />y - 39000 = 1588.4(x - 0)<em />

<em />y - 39000 = 1588.4x<em />

<em>Make y the subject of formula</em>

<em />y = 1588.4x + 39000<em />

<em />

<em>Express y as a function of x</em>

<em />f(x) = 1588.4x + 39000<em />

Solving (b): Income in 2005

<em>In 2005, x = 15</em>

So:

f(x) = 1588.4x + 39000 becomes

f(15) = 1588.4 * 15 + 39000

f(15) = 62826

Find the mean of <br>35,26,31,16,21,23,27,30,26,17,19,27​
zzz [600]

Hello!

To find the mean, we must add all the terms in the dataset and divide by how many there are.

35+26+31+16+21+23+27+30+26+17+19+27=450

There are 12 terms in the dataset, so we divide by 12:

37.5

So the mean of this set is 37.5.

Hope this helps you!
