Question

How to represent two points graphically of the inequality x-y is bigger than 0

Answer 1

x - y > 0
can be written as
x>y

Draw the graph of x = y which will be a line through the origin and at an angle of 45 degrees to the horizontal y axis

The points will be represented by a shaded area above the line.
