Answer:
For better understanding of the answer see the attached figure :
length of grid square on each axis on coordinate plane is 1 units
But here it is given to be 0.1 units.
So, in order to find the ordered pair (1.8 , -1.2) we need to first locate 1.8 on x-axis and -1.2 on y-axis
Now, as each axis one grid square equals 0.1 . So,we go 18 units on positive x -axis and mark point (1.8,0) and 12 units on negative y-axis and mark point (0,-1.2) and draw vertical and horizontal lines passing through these points respectively. And the point of intersection of these lines is our required point (1.8,-1.2)
Answer:
For finding the order pair (1.8,-1.2) in the coordinate plan he has to follow the following procedure,
Here, each axis one grid square equals 0.1.
In X -axis,
1 unit = 0.1
That is, for finding the point 1.8 in x-axis,
He has to go 18 unit right side from the origin,
⇒ he get the point (1.8,0) in X-axis.
Now in y-axis,
1 unit = 0.1
Thus, finally for finding the point (1.8,-1.2), he has to go vertically downward to 12 unit from the point (1.8, 0)
