User: Lines m and n are perpendicular. If the slope of m is zero, then the slope of n is

Weegy: No, vertical lines always have undefined slopes while horizontal lines always have slopes of zero.

User: Line j passes through the points (0, 0) and (c, d). Line k passes through the points (0,0) and (-d, c). Lines j and k are

Line j passes through the points (0, 0) and (c, d). Line k passes through the points (0,0) and (-d, c). Lines j and k are perpendicular .
slope of j = (d - 0)/(c - 0) = d/c
slope of k = (c - 0)/(-d - 0) = -c/d
d/c*(-c/d) = -1 , so they are perpendicular .

The coordinates G(7, 3), H(9, 0), I(5, -1) form a right triangle. false
GH = sqrt (3^2 + 2^2) = sqrt 13
HI = sqrt (4^2 + 1^2) = sqrt 17
GI = sqrt (2^2 + 4^2) = sqrt 20
(Sqrt 13)^2 + (Sqrt 17)^2 = 13 + 17 = 30

The length of the radius for this circle. (x - 3)² + (y - 5)² = 8 is2*2^1/2.
r^2 = 8
r = 8^1/2
r = 2*2^1/2
