If a line has a slope of 2 and contains the point (-2, 1), what is its equation in point-slope form?
O A. y-1 = 2(x-2)
O B. y-1 = 2(x+ 2)
O C. y-2 = -2(x-1)
O D. y + 2 = -2(x - 1)
SUBMIT

The point-slope form is: y - 1= 2(x + 2)

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

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
