Rhombus PINE has vertices on the coordinate plane. If the slope of diagonal PN = 1/2 , then the slope of the other diagonal, IE = ____. Type a numerical answer in the space provided. If necessary, use the / key for a fraction bar. Do not type spaces in your answer.

Answer 1

The slope of the other diagonal is -2

Explanation:

we know that

The diagonals in a rhombus are perpendicular

Remember that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

In this problem

`m_p_n*m_i_e=-1`

we have

`m_p_n=(1)/(2)`

substitute

`(1)/(2)*m_i_e=-1`

therefore

`m_i_e=-2`
