    1. The problem statement, all variables and given/known data
    which of the following is a coordinate system for specifying the precise location of objects in space?
    a. frame of reference
    b. diagram
    c. x-axis
    d. y-axis

    2. Relevant equations



    3. The attempt at a solution
    I thought it would be a diagram since it would use vectors and the x and y axis to help solve a problem but i got it wrong. so can any1 please explain?

    A frame of reference is a perspective from which something is observed. By defining your reference frame, are are defining your perspective (coordinate system).

    A diagram is just a picture. What you thought a diagram was when you said: "a diagram since it would use vectors and the x and y axis to help solve a problem". A diagram is just a picture, when you start to use vectors and axes, you just added a frame of reference to the diagram.

    x-axis: According to what? Where is the axis?
    y-axis: Same logic as above^^
