12. The pomt whose y-coordinate is 3 in the given figure is
Answers
Answer:P
Step-by-step explanation:
THE POINT "P" IS LYING ON Y AXIS WITH Y COORDINATE AS 3 .
Answer :
- a) P
Explanation :
The coordinates of the points can be written as :
- P ( 2 , 3)
- Q ( -2 , 2)
- R ( 4 , 1)
- S ( 1, 0 )
So , the point whose y - coordinate is 3 is point P .
This means that this point is 3 units away from x axis or abscissa .
The coordinates of any point A is written in the form :
- A ( x , y)
The x coordinate gives the distance of the point from y axis while the Y coordinate gives the distance of the point from X axis .
The geometry which deals with coordinates and graphs is called coordinate geometry . The x - axis is also called abscissa and y - axis ordinate.
Any planar graph has 4 quadrants :
- Quadrant 1 ( + , +)
- Quadrant 2 ( - , +)
- Quadrant 3 ( - , -)
- Quadrant 4 ( + , -)
The + , - inside bracket shows that for which quadrant , the value of abscissa or ordinate will be positive or negetive .
- For any point to lie on X - axis , its ordinate must be zero .
- For any point to lie on Y - axis , its abscissa must be zero.
