Which of the following coordinate pairs make the equation x - 9y = 12 true?
Ne4ueva [31]

Options:

(12,0)     (0,12)    (3,-1)    (0,-4/3)

Answer:

(12,0) ,  (3,-1)  and (0,-4/3)

Step-by-step explanation:

Given

x - 9y = 12

Required

Which option is true?

A coordinate point is of the form; (x,y)

So, we have to substitute the x and y values in the given equation.

A. For (12,0)

x = 12 and y = 0

x - 9y = 12 becomes

12 - 9*0 = 12

12 - 0 = 12

12 = 12

<em>This is true</em>

B. For (0,12)

x = 0 and y = 12

x - 9y = 12 becomes

0 - 9*12 = 12

- 9*12 = 12

- 108 = 12

<em>This is false</em>

C. For (3,-1)

x =3 and y = -1

x - 9y = 12 becomes

3 - 9*-1 =12

3 + 9 =12

12 = 12<em></em>

<em></em>

<em>This is true</em>

D. For (0,-4/3)

x = 0 and y = -\frac{4}{3}

x - 9y = 12 becomes

0- 9*-\frac{4}{3} = 12

0+ 9*\frac{4}{3} = 12

0+ 3*4 = 12

0+12 = 12

12 = 12

<em></em>

<em>This is true</em>

<em></em>

<em>Hence, (12,0) ,  (3,-1)  and (0,-4/3) are true values of the equation</em>

Which statements correctly describe the association between the variables A and B?
postnew [5]

Answer:

positive association

linear association

Step-by-step explanation:

It is said that two variables A and B are related when the distribution of the values of one of the two variables differs according to the values of the other.

That is, when variable A grows then variable B also grows. This is known as positive correlation

When variable A grows then variable B decreases. This is known as negative correlation.

In the scatter plot you may notice that when variable A increases then variable B also increases, in an approximately linear relationship. Therefore it can be said that there is a positive and linear association.

The answer is the fourth and fifth option.
