1. Find if the point is equidistant from the points and
sqrt((h+1)^2+(0-7)^2)=sqrt((h+3)^2+(0+2)^2)
h=37/4
Hi all,
could someone please help with the following.
1. Find if the point is equidistant from the points and
thanks
i tried using the perpendicular but this seems to be flawed.
and
the functions were then
and
therefore when y=0
should i be using the midpoint or something?
Why do you think that the value of "c" will remain same.

Visualizing it
- Two points are given
- Make a line joining these points.
- Find mid-point of the given points in the line
- Draw a line perpendicular to previous line and passing through midpoint
- The second line will intersect with x-axis at some point. The x coordinate of this point is value of "h"
Thanks ADARSH and learnmath, i got it in the end
im sure i was supposed to answer this your way learnmath, ie using pythagoras. the drawing does help a lot.
i made mistake as ADARSH says of assuming c were equal.
midpoint is
perpendicular line is
solving for by using midpoint gives our perpendicular line equation
now find the x intercept
therefore
