Plot the point (0, -4) on a graph paper.

Hint: In this type of question we have to use the concept of plotting a point on a graph paper. We know that when we consider a point (a, b) then a will represent x-coordinate and b will represent y-coordinate of that point. We have to draw a coordinate axis first that is x-axis and y-axis. Then we have to decide how many sides of the small squares may be taken as one unit such that one centimetre represents one unit on both axes. According to that unit and sign, the location of the point is found.

Complete step-by-step solution:
Now, we have to plot the point (0, -4) on a graph paper.
Let us take the length of one division of squares as one unit.
In point (0, -4) we can observe that x-coordinate is zero and y-coordinate is negative so the point will lie on the y-axis.
Now, as y-coordinate is negative the point will lie on the negative y-axis that is in downward direction.
To plot the point counts 4 units along the y-axis downward.


Note: In this type of question we have to observe the coordinates of the point as position of point depends on them. Also we have to note that the coordinates of any point on the y-axis are of the form (0, y). Therefore, the x-coordinate of every point on the y-axis is zero.
