Asked by melly

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.
Answered by oobleck
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!

How do I draw a line at 45 degrees
Answered by oobleck
the line y=x is at 45° -- its slope is 1, the tan(45°)
