If AD is the altitude to BC, what is the slope of AD?
anygoal [31]

Answer:

Option (C)

Step-by-step explanation:

If AD is the altitude to BC, both the segments AD and BC will be perpendicular to each other.

By the property of perpendicular lines,

m_1\times m_2=-1

where m_1 is the slope of the line AD and m_2 is the slope of BC.

m_2=\frac{y_2-y_1}{x_2-x_1}

     =\frac{8+2}{3-7}

     =-\frac{5}{2}

Now from the given property,

m_1\times (-\frac{2}{5})=-1

m_1=\frac{5}{2}

Therefore, slope of altitude BC = \frac{5}{2}

Option (C) will be the answer.
