# Please answer all the parts of first question...

**Dear Student,**

1.(a).Since we need to find the coordinate of the image of (-1,2,-3) in the x-z plane, a sign of its y- coordinate will change

1.(a).

So, Image of (-1,2,-3) is (-1,-2,-3)

**(b).**Since we need to find the coordinate of the image of (-1,2,-3) in the y-z plane, a sign of its x- coordinate will change

So, Image of (-1,2,-3) is (1,2,-3)

**(c).**Since we need to find the coordinate of the image of (-1,2,-3) in the x-y plane, a sign of its z- coordinate will change

So, Image of (-1,2,-3) is (-1,2,3)

**Kindly post other questions in a separate thread.**
