Which line is the graph of the equation y=3x

D

Step-by-step explanation:

Lets create a table using the equation y = 3x:

 0  x 3 =  0

  1  x 3 =  3

 2  x 3 =  6

 3  x 3 =  9

This means our coordinate pairs (x,y) will be:

(0,0); (1,3); (2,6); (3,9) ... and so on

Now, if we study the graphs, the line on graph D best represents this function.

This means the answer is D!

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
