Correct option is C. There are 20 ordered pairs.
Given that ordered pairs (x,y)
such that x is even integer where 4≤x≤10 and y is an integer.
where 4<y<10.
Then even integer 4≤x≤10 are four i:e
4,6,8,10
And integer 4<y<10 are five i:e
5,6,7,8,9
Then ordered pair are = 4×5=20
An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension. The numeric values in an ordered pair can be integers or fractions.
