1.

The graphs of the linear equations 4x - 2y = 10 and 4x + ky = 2 intersect at a point (a, 4). The value of k is equal to:1. -42. 43. -34. 3

Answer» Correct Answer - Option 1 : -4

 Given :

There are two linear equations intersect at a point (a, 4)

4x - 2y = 10 

4x + ky = 2 

Calculations :

4x - 2y = 10      ....(1) 

4x + ky = 2      ....(2) 

Solving equations (1) and (2)  we will get,

-2y - ky = 8 

-y (2 + k) = 8 

put y = 4 as intersecting points were (a,4)

-4 (2 + k) = 8 

⇒ k = -4 

∴ The value of the k will be -4
