The lines shown below are parallel. if the green line has a slope of -1/11, what is the slope of the red line?
a)-1/11
b)1/11
c)-11
d)11

Lines are parallel so they have same slopes
 if the green line has a slope of -1/11, the slope of the red line is also -1/11
answer is 
a)-1/11

Parallel lines must have the same slope and a different y-intercept.  So if one line has a slope of -1/11, any possible parallel line will also have a slope of -1/11.

The answer is lol i dont know
