To graph: The given point on coordinate plane
Answer to Problem 2.6.11EP
Explanation of Solution
Given information:
Concept used:
We know that a number line always starts with 0 and increases 1 unit at every interval.
Also, when two number lines intersect each other at right angle, it forms a coordinate plane. The vertical number line in this case is known as y-axis and horizontal number line is known as x-axis.
As the number lines intersect each other, the plane is divides into four quadrants namely first, second, third and fourth quadrant moving anticlockwise starting from positive x-axis.
When a point is located on the graph, its x-coordinate and y-coordinate together represent the order pair. Sign on the ordered pair identify the quadrant it is located in, for example for a point
Graph:
Basis the above definitions we can locate the point R on graph and write its ordered pair.
Basis the graph, the point lies in Second quadrant.
