Answer:
Because the data values selected for each sample will be different
The answer to your question is 1520. This is because the numbers after the decimal point is larger than 50, which means that it will be the next number.
The equation of a line is:
y-yo=m(x-xo)
Where (xo,yo)=(9,3) and m is the slope.
The slope of a line which is parallel to another line is the same; the slope of the line y=6x-4 is 6, then:
y-3=6(x-9)
y-3=6x-54
y=6x-51
