Answer:
y = 4
Step-by-step explanation:
Since the line in question is parallel to the x axis, we can tell that going from one end of the line to the other, x value changes, but y value always stays the same and equals 4.
Answer:
c)
Step-by-step explanation:
The asking price in Baltimore has a mean value of $286,455 and a standard deviation of $11,200; this means that most houses prices fall between $275,255 and $297,655.
Similarly, the mean value in Denver is $188,468 and a standard deviation of $8,230; most houses prices fall between $180,238 and $196,698.
The problem tells us that one home sold in each city where the asking price for each home was $193,000. In the case of Denver this would be expected (values usually fall between 180,000 and 196500 approximately).
However, the house in Baltimore is relatively farther from the mean than the one in Denver because the price is more than one standard deviation away from the mean.
Therefore, the correct answer is C. The house in Baltimore is relatively farther from the mean than the house in Denver.
Answer:
the equation of the line is 7x + y = 0 .
Step-by-step explanation:
in the standard form of the line that is Ax +By = C we can write it in the form of
By = C - Ax
which is in the form of 
where m is the slope of the line and c is y intercept made by the line.
comparing and
we get that 
and 
since it is given that slope of the line is -7 therefore m = -7 and c = 0
therefore 
and 
therefore C = 0 , A = 7 and B = 1
therefore the equation becomes 7x + y = 0
