more details,so I can give you an answer
This is a TERRIBLE answer but theirs math websites that give detailed steps.
Law of Detachment means 1. if p then q and 2. p then we can derive a 3rd true statement 3. q
Law of Syllogism means that if the following two statements are true 1. if p then q. 2. if q then r. Then we can derive a third true statement 3. if p then r.
So the difference is one has only p and q and the other has p q and r.
Slope: rise over run, for any straight line. Example: y=mx + b
Constant of proportionality: a constant by which you multiply your independent variable (x) to get a specific value of the dependent variable (y). Example: y=kx.
The main difference here is that y=mx+b may or may not pass through the origin, whereas y=kx always passes through the origin.
Both k and m are "slopes," with k pertaining to direct variation y=kx, and m pertaining to slope of a line which may or may not pass through the origin.
In this limited sense, both k and x are slopes. k could be the slope of a straight line passing thru the origin, same as m, but m could not be the constant of proportionality if the line in question does not pass through the origin.
Ok so
basically solve for y
2x+18y=36
subtract 2x from both sides
18y=-2x+36
divide both sides b 18
y=-1/9x+2
