Question
The line L given 
= 1 passes through the point (13, 32). The line K is parallel to L and has the equationx 
. = 1. Then the distance between L and K is
= 1 passes through the point (13, 32). The line K is parallel to L and has the equationx . = 1. Then the distance between L and K isOptions
A.
B.
C.
D.
Solution
Slope of line L = - 
Slope of line K =
Line L is parallel to line k.
⇒
⇒ bc = 15
(13, 32) is a point on L.
⇒
⇒ b = - 20 ⇒ c = -
Equation of K: y - 4x = 3
Distance between L and K =
Slope of line K =
Line L is parallel to line k.
⇒
⇒ bc = 15(13, 32) is a point on L.
⇒
⇒ b = - 20 ⇒ c = -
Equation of K: y - 4x = 3
Distance between L and K =
