you need to get out some graph paper
label the axes so that distances of 400 can be easily drawn
draw a line at 45° (y=x) so it goes 400 in both x and y directions
Don't forget your Algebra I now that you're doing physics!
A man walks 400 m in the direction 45 degrees north of east. Represent this vector graphically by selecting a scale and drawing a coordinate system.
I do not know how to answer this question.
