Answer 2

☞QUESTION:-

if (-2,2) is one sloution of 2x+ky+6=0 find the value of k ?

☞SOLUTION:-

This is a very basic question of class 8th or 9th standard.

As, this is given to us the coordinates of x and y components which is given in th2 linear 2 variables Equation!!

Equation:- 2x+ky+6=0

The various decisive answers can be calculated,

but for finite line equation and given coordinates pointa we get,

Before moving to the final answer lets memorisr few points.

These kinds of questions can easily be solved by keeping the coordinates rather, Going for substitution Equations.

Also,

Main point of the question is to find the corresponding points which satisfy the given Equations!!

Now, moving to question with the coordinates (-2,2) and equation, 2x+ky+6=0.

we get,

=> 2(-2)+k(2)+6=0

=> -4+2k+6=0

=> 2k+2=0

=>2k= -2

=> k= -2/2

=> k= -1

So, the value satisfying the given equation 2x+ky+6=0 is K= -1 .
