What are the missing coordinates? My teacher said it was (h-m,n), but I’m saying it is (h+m,n). Could anyone help?

Answer:

  • You are right, the coordinates are:


(h+m,n)

Step-by-step explanation:

Here is how you can proove that you are right.

Note that m is the x-coordinate of the point
(m,n) . Since this point is to the left of the y-axis, it is a negative number, but the negative sign is included in
m.

The distance from
(m,n) to the y-axis is not
m but
-m.

That is the same distance from the point with the missing coordinates to the point (h,0).

Then, the missing x-coordinate is
h-(-m)=h+m.

Of course, there is not doubt about the y-coordinate: it is n, because the point with the missing coordinates is at the same height as (m,n).

Hence, the missing coordinates are x = h+m, and y = n: (h + m, n).
