Y = x - 4

First find the slope of the two coordinates.
Slope is the change in y over the change in x

Y2-Y1 / X2-X1

26-9 / 30-13

17/17 or 1

Now we have
y = 1x + b

To find b, plug in one of the x,y coordinates into this equation

9=1(13) + b
9 = 13 + b
Subtract 13 from each side

-4 = b

So the answer is

y=x-4

Nikolay [14]

The system of inequalities models correctly the number of cookies is c + b ≥ 125 and 8c + 12b ≤ 2000

Let c represent the number of cookies and let b represent the number of brownies.

Since Genie want to make more than 125 cookies and brownies altogether, hence this is given by:

c + b ≥ 125 (1)

Also, Genie has a total of 2,000 grams of flour, hence:

8c + 12b ≤ 2000 (2)

Therefore the system of inequalities models correctly the number of cookies is c + b ≥ 125 and 8c + 12b ≤ 2000

Answer:

Correct option: e) a two-way table.

Step-by-step explanation:

In this case the store wants to see whether there is a relationship between the satisfaction level of the customer and their gender.

In statistics when there is a need to analyze or derive a relation between two categorical variables one should use a two-way table.

Categorical variables are qualitative variables that take on specific values that are usually labels. For example, grades obtained in an exam, gender, etc.

In this case the two categorical variables are: Gender and Satisfaction level.

To study the relation between the gender of a customer and their satisfaction level use a two-way table.
