All points whose y-coordinate is twice its x-coordinate.
If Y = 0 then there is no value of X such that XY = 1.
x=2
Assuming 6 refers to the value of x, the y coordinate is 1
I suggest "boring".

This is a point on the cartesian coordinate plane... (10,13)

Check your text book for how to solve it.
There are infinitely many coordinate pairs - the coordinates of each point on the infinite line defined by the equation.
I suggest "boring".
x = -6 and y = 1
It is a horizontal line (slope of 0) which intersects the coordinate (0,5).
