A) y=6x-7
b) y=1/4x+8
c) y=4x+8
d) y=-1/4x-7

Symmetry? lol

I guess you would need to find the perpendicular.
The slope of that line is 4.

The negative reciprocal is -1/4.

Now what's confusing now, is that both D and B works because the intercept does not influence symmetry between the two lines; only the linear slope does. I can't help with that. 

The answer is b i’m sure

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
