slope intercept form has the y by itself on one side
so try to get y all alone first

I think it is d

a) y = -5/12x+11/12; slope: -5/12; y-int.: 11/12
b) y = 5/12x-11/12; slope: 5/12; y-int.: -11/12
c) y = -5/12x-11/12; slope: -5/12; y-int.: -11/12
d) y = 5/12x+11/12; slope: 5/12; y-int.: 11/12

mmm be careful ^_^
-5x - 12y = 11
+5x +5x
-12y = 5x + 11
/-12 /-12 /-12
y = -5/12 x - 11/12

oh. so is it c?

yes :) but do you see where you got it wrong? :P

I accidentally thought that when you divided two negatives it would be positive.
jigglypuff314 (jigglypuff314):
well yeah, but you weren't dividing two negatives here
