If the point ((4,-2) what is included in a direct viration relationship which point also belongs and variation

Answers

Answer:

The answer is "This direct variant (-4,2) is part of it".

Step-by-step explanation:

The equation expresses its direct variation relation

$y = mx ........ (1)$

Where x and y vary directly, and k vary continuously.

Now so the point (4,-2) is in the direct relation of variation, so from equation (1) we are given, $-2 = 4m$

$\to m=-(1)/(2)$

The equation (1) is therefore converted into

$\to y=-(1)/(2)x \n\n\to x + 2y = 0 ......... (2)$

Then only the point (-4,2) satisfies the connection with the four possibilities (2). Therefore (-4,2) is a direct variant of this.
