Question

geometry

Answer 1

(2,-5,3) by inspection using coordinates (x,y,z)

Answer 2

he is correct, are you seeing how he is getting these? the lines coming off of q to make a rectangle, are guiding you to the position of the axis. for the x axis, just look for the x numberline. there is a very light colored purple box that is connected at point q. follow it to where it hits the x numberline and that is your x. do the same for y and z. For y, that little dotted line square is the one that touches the y numberline. see how it connects to q also? that is your y value. The Z is the top box which is darker purple.
