2, 3, 4, 5, 6, 7. Is the correct answer
The correct answer is parallel
When a line passes through the two points
, its slope is given by the formula 
In this question, a line L passes through the points 
So, its slope is given by

When two lines are perpendicular, then the product of their slopes is -1.
Since, the slope of the line L is
, so the slope of the line which is perpendicular to the given line L is
as the product of
.
Unit conversions will almost always fall into a division or multiplication problem. In this case we are being asked to convert a smaller unit to a larger one, so it will be a division problem.
The standard metric goes on the bottom of the fraction always, so 10/16 or 10÷16 is the problem.
10÷16= .625 pounds of cheese.
