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

1. Reiny

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)

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.
