Two point charges of the same magnitude but opposite signs are fixed to either end of the base of an isosceles triangle. The electric field at the midpoint M between the charges has a magnitude EM. The field directly above the midpoint at point P has a magnitude EP. The ratio ...

**Graphs**

The vertices of a triangle are A(13,13), B(9,3), and C(-1,1). Determine the equation of the median AM, where M is the midpoint of BC. Midpoint M of BC = ((9-1)/2,(3+1)/2) =(4,2) slope AM = (13-2)/(13-4) = 11/9 So the equation of the median is 11x - 9y + c = 0, (knowing that ...

**Finding a Formula, help please !**

Does anyone know the formula to find any point between two other given points in a line? Please, and thank you! The mindpoint formula xm= _(x1 + x2) /2 ym = (y1 + y2) /2 This give the midpoint (xm, ym) between the points x1,y1 and x2,y2 Thanks for the tip, but I was wondering ...

I am trying to find the coordinates of a point in a line. I have one end, and I have the midpoint. What formula should I use to find the one on the end? The one end is (8,4) and the MIDPOINT is (14, 7). What would I do to find the opposite point?! thanks!
