Answer:
Lines BC and F represent perpendicular lines
Step-by-step explanation:
we have
<em>Line BC</em>
the slope of the line BC is
<em>Line F</em>
the slope of the line F is
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
so
-----> slope line BC
-----> slope line F
Find the product of their slopes
therefore
the answer is A.
to get the you would use the distributive property to multiple the 4 by the two term in the parentheses.
