Answer:
The gradient of the graph below is 
Step-by-step explanation:
We need to calculate the gradient of the graph
The gradient of graph is actually slope of the graph.
The slope of graph can be calculated using formula: 
Taking any 2 points on graph i.e
(1,0) and (-1,-3)
We have 
Putting values and finding gradient:

So, The gradient of the graph below is 
R = (p,p)
S = (p,0)
Since the shape is a square, each side should have the same length, <em>P</em>.
