The simplest equation that can contain two points is a linear equation,

Here we will find that the line equation is

$y = (3/2) \cdot x$

A general linear equation is:

$y = a\cdot x + b$

Such that a is the slope, and b is the y-intercept.

If we know that the line passes through the points (x₁, y₁) and (x₂, y₂), the slope can be written as:

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

Here we know that our equation must pass through point C, (6, 9) and through point O, the origin, or just (0, 0)

Then the slope of our equation will be:

$a = \frac{9 - 0}{6 - 0} = 9/6 = 3/2$

Then our equation is something like:

$y = (3/2) \cdot x + b$

To find the value of b, we can use the fact that the line contains the origin (0, 0)

This means that when x = 0, we also have y = 0.

Replacing that in the above equation we get:

$0 = (3/2) \cdot 0 + b\\\\0 = b$

Then the equation of the line is:

$y = (3/2) \cdot x$

The equation of line that passes through O(0,0) and C(6,9)

$y=\frac{3}{2} x$ .

Step-by-step explanation:

Given

In xy- plane above , the coordinates of point C =(6,9)

The coordinates of point of O=(0,0)

We know that the equation of line that passes through two points $(x_1,y_1) \; and (x_2,y_2)$

$\frac{y-y_1}{y_1-y_2} =\frac{x-x_1}{x_1-x_2}$

x_1=0, y_1=0

x_2=6, y_2=9

By substituting the value of $x_1,y_1,x_2 \;and \; y_2$ in the above formula

The equation of line that passes through the points (0,0) and (6,9) is given by

$\frac{y-0}{0-9} =\frac{x-0}{0-6}$

The equation of line that passes through the points O (0,0) and (6,9) is given by

$\frac{y}{-9} =\frac{x}{-6}$

The equation of line is given by

$y=\frac{3}{2} x$

Hence, the required equation of line that passes through the points O (0,0) and C(6,9)

$y=\frac{3}{2} x$

a 4/6 = 9/12 not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional. if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional

b 2/3 = 12/18

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
