Question

find the value(s) of p , if the lines represented by these equations 3x - y - 5 = 0 and 6x -2y - p = 0 are parallel​

Answer 1

Step-by-step explanation:

if the two given lines are parallel, then

a1/a2 = b1/b2 ≠ c1/c2

3x - y - 5 = 0

6x - 2y - p = 0

a1/a2 = 3/6 = 1/2

b1/b2 = -1/-2 = 1/2

therefore for two lines to be parallel,

c1/c2 ≠ 1/2 => -5/-p ≠ 1/2

then p can be any number other than -10
