Question

For what value of k the equation x - 4 y - 9 = 0 and 2x - k y - 27=0 is equal to zero the president intersecting line

Answer 1

Answer:

to get intersecting line on the graph , w

Step-by-step explanation:

To get an intersecting lines ,we must get the answer equal to 0..

steps:take any 2 values of x say : 0,1,2......

I take value of x to be 1

so, x - 4y - 9 = 0

(x = 1)

1 - 4y - 9 = 0

so -8 = - 4y( the sign ' minus ' needs to get cancelled )

4y = 8

y = 8 / 4

y = 2 //

similarly , we get the equation

2x - ky - 27 = 0

(where x and y are 1 and 2)

2*1 - k*2 - 27 = 0

2 - 2k - 27 = 0

- 2k = 25

k = - 12.5

Sana here !

hope it helps !
