The given information is the coordinates of the 3 points:
(2,6)
(7,4)
(4,0)
Each pair of coordinates is given by (x,y), x is the coordinate at the x-axis and y is the coordinate at the y-axis.
To plot the points we need to trace an imaginary vertical line through the x-coordinate and an imaginary horizontal line through the y-coordinate, the point where these lines intersect each other is the location of the given point.
Let's start with (2,6):
Now, let's continue with (7,4):
And finally, let's plot the point (4,0):
There we have the three given points in the coordinate plane.
