Determine the slope of the lines. line 1: y=9
line 2: x=-3
are the slopes parallel, perpendicular, or neither?

entering that problem on the tube might get you an answer

y > 1/3x

y < = -x + 4

hope this : )

ou would have 12 of each

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
