The slope-intercept form: y = mx + b
(m - slope, b - y-intercept)
We have y = -2. It's the slope intercept form where m = 0 and b = -2.
y = -2 → y = 0x - 2

Each bottle of apple juice has 2 litters of juice, so, if he bought y bottles of apple juice, we will have to multiply.
12 liters of apple juice3 liters of orange juice
The linear relationship which exists between the change in weight and number of days of hibernation in a hedgedog can be modeled using the equation y = - 0.03 + 0
- Change in weight per day of hibernation = - 0.03
- Change in weight for 115 days = - 3.45 ounces
A linear model can be created using the data in the table given using a regression calculator or excel ;
The linear model obtained in the form y = m + bx is :
- y = - 0.03x + 0
- y = change in weight
- x = number of days of hibernation
- Intercept = 0
- Slope = -0.03
- The slope value of the function gives the change in weight value per number of days of hibernation ; which is -0.03.
- Using the regression equation, substitute, the vlaue of x = 115
- -0.03(115) + 0 = - 3.45
Therefore, the change in weight after 115 days of hibernation is - 3.45 ounces.

Answer:
The study is an experiment.
Step-by-step explanation:
From the information provided, Eighth-grade students are randomly divided into two groups.
==> The first group is taught English using traditional techniques.
==> The second group is taught English using a reform method.
The main goal is to compare the proficiency in English of the two groups. This is purely an experimental study. In this case, human experiment.
The experimental tools is the English techniques being served or taught and the experimental units are the Eighth-grade students which were grouped into 2 groups and served different techniques.
At the end of the study, the researchers wish to know the most effective or efficient method of teaching English to gain excellent proficiency of the language. They should be able to know whether Traditional techniques is better than the Reform method or vice versa.
