Question

How do you plot a graph for a decimal number with coordinates $$A(3.5,4)$$ on a coordinate graph?

Answer 1

Hint: We will first find out the $$x$$ and the $$y$$ coordinates according to the question and then plot it in the graph. A coordinate graph is a diagram representing two number lines. One is the horizontal line called the $$x$$ axis and the other one is the vertical line called the $$y$$ axis. These two number lines are perpendicular to each other.

Complete step by step solution:
According to our question, we can say that we are having coordinates of a point on the graph. The coordinates are $$(3.5,4)$$ and the point is $$A$$. When we are using a coordinate graph, we need to write the coordinates in a form that is $$(x,y)$$. Here, $$x$$ is a point on the x-axis and $$y$$ is a point on the y-axis.
So, if we see our question according to the form, then our $$x$$ coordinates is $$3.5$$ and $$y$$ coordinate is $$4$$. Now, we will plot the graph according to the coordinates given.
We will start with the $$x$$ axis first. We can see that the coordinate of the $$x$$ axis is positive. So, our point will be somewhere in the top right side of the graph. We will start from the origin first which is $$0$$. Then we will go $$3.5$$ units to the right side of the graph on the $$x$$ axis. We can point to the place when we reach $$3.5$$ units.
Now, we will start with the $$y$$ axis, and we will go to $$4$$ units up on the axis because the $$y$$ axis is in vertical position. And now when we reach our mark, we can point it and write the coordinates of $$x$$ and $$y$$. Therefore, our plotting is done. We get our graph like this:
  

Note: The coordinate graph has two axes which are the horizontal $$x$$ axis and vertical $$y$$ axis. These two axes not only have positive axes, these also have negative axes downwards. There is also a $$z$$ axis which is used while 3-D graph plotting.
