QUESTION:
Find the distance between each pair of parallel lines.
y = -3y = 1
ANSWER:
d = 4
Sec 3-6 30 points
QUESTION:
Find the distance between each pair of parallel lines.
y = 4xy = 4x – 17
ANSWER:
y = -(1/4)x-(1/4)x = 4x – 17 -(17/4)x = -17 x = 4y = -(1/4)(4) = -1Distance between (0, 0) and (4, -1) is √17
Sec 3-6 40 points
QUESTION:
Find the distance between each pair of parallel lines.
x + 3y = 6 x + 3y = -14
ANSWER:
y = 3x + 23x + 2 = -(1/3)x – (14/3) (10/3)x = -(20/3) x = 2y = 3(2) + 2 = 8Distance between (0, 2) and (2, 8) is 2√10
y = -(1/3)x + 2y = -(1/3)x – (14/3)
