Elia is solving the following system below by substitution. {3x+y=104x−3y=−12 Which of the following would be a step in solving the system? Substitute y+10 for x in 4x−3y=−12. Substitute −y+10 for x in 4x−3y=−12 Substitute −3x+10 for y in 4x−3y=−12 Substitute 3x−10 for y in 4x−3y=−12

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

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
