Question

In 3-spnoe the oquations =+y=0,2=0 describe None of the above is correct. a plane parallel with the zy-plane. z plane orthogonal to the maxis. a lite orthogonal to the y-plane. a line parallel with the = nxis.

Answer 1

. Here sires canadiuns nty=0 Z=0 As both are eanations of planes seperately so combine egnation will gire intersection of neon So As two plones intersect at a line. so ntyzo and zio represent a line Now we will crite eanation or standeod form 2-1 = Y-Y line in Z-7, Z co nty=0 2 n - n-o yao Lab, c) al line. So direchin veche به راس را / at L1,-1, o gires a vecho per pendicular to a Z axis.. 'Ano vecho alone z coot <1,-1,0). Lo,0z)=0 and dor poodnat o implies peopendicular, veckor all vecho peopendicular to 7-any is possalled to xy plene so line is parallel to xy plone. In bad line lie on xy plone So None of siren ophion Correct Now
