A spring was at its resting position where it is attached to a wall at its left side and a block at its right side as shown. The spring constant k- 75.0 N//m. The block is moved leftwards and the spring's right end is displaced from the position of 0.200 m to 0.300 m where it is held in place. All positions are measured from the origin O of the wall. What is the spring force exerted on the block?

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
