He can only pick 7 different groups because 2 times 7 is 14, and there are 15 people in all.

Hope this helps. c:

Consider the line x-2y=-1 What is the slope of a line parallel to this line? What is the slope of a line perpendicular to this l

Paul [167]

Answer:

slope of line that is parallel is 1/2

slope of line that is perpendicular is -2

Step-by-step explanation:

parallel lines have the same slope

perpendicular lines have slopes that are opposite and reciprocal

x - 2y = -1

-2y = -x -1

y = 1/2x + 1/2

the coefficient of the 'x' term represents the slope
