How do you calculate the slope of a vector on a graph?
Lets say for example vector AB with coordinates (5,4).

rise over run.
y / x
i'll assume that your vector starts from the origin (0,0)
x = 5, y = 4 makes a line pointing northeast (roughly)
slope = 4/5 = a positive slope (which agrees with our assumed drawn diagram)
it's positive because it's not travelling downward. or backward (depending on how you label your axes)

Vector AB is 5 along and 4 up.
Draw a right angled triangle ABC such that AC is horizontal = 5 and BC is vertical = 4
Slope = tan A = 4 / 5

The slope is 4/5. It is just the 'y' value over the 'x' value.
Slope is easy, slope is fun, slope is rise over run.
Just a little rhyme my teacher taught us. ^^

If you have this only as given you can't since it is only a point on a graph and you cant draw a line with it...
