Answer:
Equation of the line in question: 
.
Step-by-step explanation:
Start by finding the intersection of the two straight lines. The equation for both lines shall hold at their intersection. (Using the idea of the Gaussian Elimination.)
.
Add -3 times the first equation to the second:
.
Add the second equation 
to the first:
.
Hence the intersection of the two lines will be 
.
Now, find the slope of that straight line. 
is equivalent to 
. The slope of that line is equal to 1. So will be the slope of the line in question.
Apply the point-slope form of a line on a Cartesian plane:
- Point: ,
- Slope:
.
Equation of the line:
.
Simplify to obtain:
.

Answer:
a
Step-by-step explanation:
Answer:
A. This study is an experiment, since it was based on a random sample.
Step-by-step explanation:
Simple random sampling is a probabilistic sampling procedure that gives each element of the target population and each possible sample of a given size the same probability of being selected.
