40Use the graph to determine the slop of each segment of the quadrilateral. The line containing
and the line
containing
(up 1 unit, right 3 units). Therefore one pair of sides is parallel. The slope of
4-4 Parallel and Perpendicular Lines
is undefined and the slope of
, so they are not parallel. ABCD is a trapezoid.
CDEF is a kite. Are the diagonals of the kite perpendicular? Explain your reasoning.
Use the graph to determine the slope of each diagonal. The slope of
(up 2 units, right 3 units) and the slope
of
is
reciprocals.
y = 6x + 4 and y =
are perpendicular. Explain.
The slope of y = 6x + 4 is 6. The slope of y =
is
. The slopes are opposite reciprocals, so y = 6x + 4 and y
=
On a map, Elmwood Drive passes through R(4, 11) and S(0, 9), and Taylor Road passes through J(6, 2)
and K(4, 5). If they are straight lines, are the two streets perpendicular? Explain.
Find the slope of Elmwood Drive (
).
Find the slope of Taylor Road (
).
