The gradient is defined by the RISE divided by the RUN

 

Mouse over graph for gradient calculation
Positive gradient (uphill)
Negative gradient (downhill)

Gradient?

Mouse-over "key words"

 

Remember 'uphill' = positive gradient
     & 'downhill' = negative gradient

Gradient calculations can be done from the coordinates only (x1,y1) & (x2,y2)
