Which undefined geometric term is described as a location on a coordinate plane that is designated by an ordered pair, (x, y)?

distance
line
plane
point

The ordered pair  in allocation on the coordinate plane is called .

Further explanation:

The vertical line represents  axis and the horizontal line represents   axis in coordinate plane.

The  axis and  axis perpendicular to each other at the origin.

The origin is the point where the value of   are zero and it can be represented in the ordered pair form as .

These  axis and  axis divide the coordinate plane into four quadrants.

Both  are positive in the first quadrant.

The value of  is negative and the value of   is positive in the second quadrant.

Both  are negative in the third quadrant.

The value of   is positive and the value of   is negative in the fourth quadrant.

In the ordered pair  of the coordinate plane, the first number represents the  coordinate that is known as abscissa and the second number represents the  coordinate that is known as ordinate.

The ordered pair  in a location on the coordinate plane is called point.

Therefore, the option  is correct.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
