I got this question wrong on my test. Could some one please show me the steps?
Choose the equation below that represents the line passing through the point (-2,-3) with a slope of -6. Choices are y+3=-6(x+2) and y-3=-6(x-2).

y - y1 = m(x - x1)
m = -6
y1 = -3
x1 = -2
now lets sub our values in
y - (-3) = -6(x -(-2)
now what can you do with this ?

anonymous · Answer

simplify to y-3=-6(x-2) it looks so easy written out like that. Thank you

texaschic101 · Answer

wrong....
y -(-3) = -6(x - (-2)
y + 3 = -6(x + 2)
two negatives multiplied together equal a positive

understand ?

anonymous · Answer

I keep making the same mistake.  There are no exceptions to the two neg rule?

texaschic101 · Answer

keep practicing...you will get it. No exceptions...negative multiplied by negative = positive.
