Question

What is the ordinate of the point \[D\]?

Answer 1

Hint: To find the exact location of the point \[D\] or the coordinates of the point \[D\] we find its distance in the \[x\] axis and \[y\] axis from the origin. Here to find the ordinate of the point \[D\] the distance from the origin of the point \[D\] on the \[y\] axis is enough.

Complete step-by-step solution:
We observe on the coordinate plane that the point \[D\] is \[6\]a unit's distance away on the left side of the origin or the point \[(0,0)\] which is the intersection point of both the axes known as the \[x\] axis and the \[y\] axis.
That is the point \[D\] is \[6\]units left to the origin i.e. the abscissa of the point \[D\] is \[ - 6\].
Now, we find its distance on the \[y\] axis i.e. the point \[D\] is \[4\] units above the origin which implies that the ordinate of the point\[D\] is \[4\].
Hence, the ordinate of\[D\] is \[4\].
Additional information: The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane or the coordinate plane. We know that the coordinate plane has two axes viz. \[x\]- axis and \[y\]-axis and are at right angles two each other. We calculate all the points with reference to the origin or the point which is the intersection of both the \[x\] axis and \[y\] axis. The abscissa is the coordinate of the \[x\] axis and the ordinate is the coordinate of the \[y\] axis of the given point.

Note: It is very important that we know the terms related to the coordinate axes. The distance above the origin on-axis is taken as positive and below the origin is negative. Similarly, the distance on the right side of the origin on the \[x\] axis is taken as positive, and to the left of the origin is taken as negative.
