Question

Which point lies in the plane represented by the question

Answer 1

Given:

Equation is:

`2x+7y+3z=-25`

Find-:

The point represents by the equation

Explanation-:

The point satisfied the equation,

`\begin{gathered} 2x+7y+3z=-25 \\ \\ (x,y,z)=(-6,-4,5) \\ \\ =2x+7y+3z \\ \\ =2(-6)+7(-4)+3(5) \\ \\ =-12-28+15 \\ \\ =-25 \end{gathered}`

So, the point ( -6, -4,
