Question

How do you plot the ordered pairs on the rectangular coordinate system \[(5.1,3.2)\] and \[(-2.5,4.9)\]?

Answer 1

Hint: From the question we are asked how can we plot the given ordered pairs on a rectangular coordinate plane. So, for solving this question we will take the values of x on the right and left of the plane and we will take the values of y ordinate to the top and bottom of the coordinate plane. Thus, we plot the given points.

Complete step-by-step solution:
Generally, to plot the given points or any other points on the coordinate grid:
For x value go to the right if the number is positive and we go to the left if the number is negative.
Then for the value of y ordinate we will go up if the number is positive and we go down if the number is negative.
For the first plot \[(5.1,3.2)\]
Because the x value is positive go to the right \[5.1\] from the origin and then go up \[3.2\] as the y value is also positive.
For the second plot \[(-2.5,4.9)\]
Because the x value is negative go to the left \[2.5\] from the origin and then go up \[4.9\] because the y value is positive.
So, the graph will be as follows.

Note: Students should know how to plot points in a graph. We must know the coordinate plane system very thoroughly to solve questions of this sort. We must keep in mind that for negative points of x we will go to the left of origin and for negative y points we must go to the bottom of origin. We should not confuse this or else our solution may become wrong.
