Answer:
The equation is 
Step-by-step explanation:
If we want a line parallel to the line in the problem it will have the same slope. The equation given in the problem is already in slope intercept form so we can take the slope for the new equation directly from this equation.
The slope-intercept form of a linear equation is: 
Where m is the slope and b is the y-intercept value.

Therefore the slope is

We can now use the point-slope formula to write the equation of the parallel line:
The point-slope formula states:

Where m is the slope and
is a point the line passes through.
Substituting the information from the problem gives:


Or, we can solve for y to put the equation in slope-intercept form:




Answer:
Step-by-step explanation:
1)Population of Interest : All UC Berkeley Undergraduates
Sample : 129 UC Berkeley Undergraduates
2)
Can the results of the study be generalized to the population of interest?
No, because the sample is not representative of the population since it consists of only UC Berkeley undergraduates.
3)
No, because the the study is observational.
Rotation 90° translates (x, y) to (-y, x). Thus (3, 2) gets translated to (-2, 3). Your green box gets filled with -2.
