Answer:

-\dfrac{1}{25}

Step-by-step explanation:

Given the rhombus CDEF, sides FC and CD are adjacent sides.

Using coordinate geometry, to proof that a quadrilateral is a square, with regards to the slope, the slope of adjacent segments must be negative reciprocals.

In fact, by definition: Two lines with slopes m_1$ and m_2 are perpendicular if:

m_1=-\dfrac{1}{m_2}

Therefore if :

  • FC and CD are adjacent segments
  • Slope of FC=25

For the rhombus to be a square:

Slope of CD =-\dfrac{1}{25}
