Question

If the lines given by3x -4y+7 =0, kx+3y-5 = 0are parallel, then the value of k is 

Answer 1

Answer:

the value of k is -9/4

Step-by-step explanation:

if these lines are parallel

then their slope must be same

slope for the line ax+by+c=0

is -coeficient of x /coefficient of y

here slope of 1st line is 3/4

and slope of 2nd line is -k/3

so if these are parallel lines then

3/4=-k/3

k=-9/4
