Need help with a 'x' and 'y' axis based question (Television screen sizes)

[NightKnight]

Hi there, I'm so sorry to worry you all with this, but I'm stumped. The question goes as follows.

Television screen sizes are given in inches and represents the diagonal length of the screen. The coordinate system on a television screen has the origin at the top left corner, with the positive 'y' axis going down and the positive 'x' axis going right. Work out at which coordinates (in inches) the top left corner of a standard resolution picture will display on a 39'' High Definition television screen.

All we are given is that an HD tv has a resolution of 1920x1080 and a standard tv is 800x600. Im not sure what to base the graph on, as I know that a 39'' television screen has a measurement of 19,1 x 33,9 inches.

please if anybody could assist me.

You are told the origin is at the top left corner, so all you need to do is state the coordinates of the origin...

Draw a set of axes. Place the TV screen on the axes with the top left corner at the origin.
