The gradient is defined by the RISE divided by the RUN


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


Some other graphing websites   Gradient website  Web site  for y = mx + c
Or do a Google search on line graph gradient

Gradient using coordinates

Finding the gradient of the line AB
 A(-2,4) B(2,-1)


Mouse-over "key words"


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

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