Question 173522
What is the relationship between the number of lines and the number of kilometers on the grid?

I assume you are talking about the coordinate plane, right?

I would let x = the number of lines and y = the number of kilometers for this example.

So, for example, if we are given the value of x to be 7 lines, we could figure out how many kilometers this amount of lines represents in terms of the y-axis by plotting the point in the form (x,y) correctly on the coordinate plane.

==========================================================================

Why was it so important to plot the originals points accrately?

For example, if we let x = 4 and y = 3 and plot the point (4,3), we would be further away from the origin [the point (0, 0)] on the coordinate plane and thus closer to the x-axis.

The point (4,3) is very different, say, from the point (3,4), which is a point closer to the origin and higher above the x-axis.

It is very important to learn how to plot points correctly.

It will make your math journey very easy regardless of course.
