evaluate the value of extension ( x) which elongate under the action of load (w) of 6 N ? [Use your results obtained from rest 1 ]

please help me How i can solve this question because I don't understand it clearly

Experience as follows :

First, we put spring on the board and a paper under spring to measure the distances between each point from the beginning to the end point of extension for each weight

Then we increased laod to ( 0.2 n ) the measurement was between the starting point until end point of extension is 51 mm (( same steps for all load ))

Then we've decrease the weights ( Every time one ) from end ( 0.5 ) to (0,1 ) we got same measurements

then We calculated the average by calculat increases and decreases and divide by 2

For information, there is a Positive relationship between weight and extension

plese help me
