A line has a slope of -6 that passes through the point (-12,5).
What is the equation of the line?
a. 6x + y = -77 <-- or C?
b. 6x + y = -67
c.-6x + y = 77
d.-6x + y = 17
Of the two choices, only a) and b) have a slope of -6
(-12,5) does not satisfy a) but it does satisfy b)
so b)posted by Reiny
you just need to remember your point-slope form of a line, and you get
y-5 = -6(x+12)
Then just rearrange as needed.posted by Steve
