Question

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

Answer 1

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.
