a. If x = a and x = -a, then how to calculate and what will be the graph? ( where a > 0 )

b. If y = b and y = -b, then how to calculate and what will be the graph? ( where b > 0)

For the lines, x = a and x = -a, with a > 0: the graph will be a pair of vertical lines, one passing through the point (a,0) and the other passing through the point (-a,0). There will be no 'solution' beccause there is no point of intersection.

For the lines, y = b and y = -b, with b > 0: the graph will be a pair of horizontal lines, one passing through the point (0,b) and the other passing through the point (0, -b). There will be no 'solution' because there is no point of intersection.

It would be very very useful if you provide a graph. Could you provide a graph please, sir?

a. https://www.desmos.com/calculator/v50rjzsxtt

Since a can be any value > 0 , the graph will be different for each possible value of a .

(You can pick a different value for a with the slider.)

b. https://www.desmos.com/calculator/te6iwcz85v

Like the first graph, this graph will be different for each possible value of b .
