Jason is pulling a box across the room. He is pulling with a force of 10 newtons and his arm is making a 78 angle with the horizontal, if the box weighs 28 newtons what is the net force on the
box in the vertical direction? Treat up as the positive direction, and down as the negative direction.

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.
