## anonymous one year ago how to do you write coordinates for an x y and z graph if the point is not on one of the lines?

it looks like your point has so much x, about the same amount of y, and z=0 (no up/down)

3. phi

imagine starting at the origin and walking along the x-axis until you are as close as you can get to the point (i.e. if you continue walking on the x-axis you would be moving further away). then walk in the y direction until you are as close as possible. At this point you should be directly above or below the point (if you are not at it!). go up or down until you are at the point

ok and going down the x axis from the origin is positive right? and also, would the y value be the number of spaces i moved from the x axis or the invisible number in the y line?

thanks phi i got it

x axis from the origin is positive right? that depends on which direction is labeled positive. In your picture, you move along the positive x-axis assuming you are using a standard "right-handed coordinate system" *** y value be the number of spaces i moved from the x axis or the invisible number in the y line?**** the distance you move from the x-axis (in the y direction) should match the number on the y-axis. |dw:1439498607337:dw|
