Answer:
The correct option is B . (-1, 3)
The Point A is left of one unit Y -axis and above 3 unit X-axis, therefore the coordinates of point A is ( -1 , 3 ).
Explanation:
Given:
Point A is on the Graph.
To Find:
coordinates of point A = ?
Solution:
Graph consist of X -axis and Y-axis
The intersection of X -axis and Y-axis is called as Origin.
Origin coordinate is ( 0 , 0 )
Coordinate is always given as ( x-coordinate , y-coordinate ) i.e ( x , y ).
So above X-axis y-coordinate is Positive, and below X-axis y-coordinate is Negative.
Similarly, Right of Y-axis x-coordinate is Positive, and Left of Y-axis x-coordinate is Negative.
The Point A is left of one unit Y -axis and above 3 unit X-axis, therefore the coordinates of point A is ( -1 , 3 ).
