<h2>[A] Plane S contains points B and E.</h2>
False
As indicated in Figure A below, Plane S contains only point B (remarked in red). Point E (remarked in blue) lies on plane R.
<h2>[B] The line containing points A and B lies entirely in plane T.</h2>True
As indicated in Figure B below, the line containing points A and B lies entirely in plane T. That line has been remarked in red and it is obvious that lies on plane T.
<h2>[C] Line v intersects lines x and y at the same point.</h2>False
As indicated in Figure C below, line v intersects lines x and y, but line x in intersected at point B while line y (remarked in red) is intersected at point A (remarked in blue), and they are two different points, not the same.
<h2>[D] Line z intersects plane S at point C.</h2>True
As indicated in Figure D below, line z that has been remarked in yellow, intersects plane S at point C that has been remarked in blue.
<h2>[E] Planes R and T intersect at line y.</h2>True
As indicated in Figure E below, planes R and T intersect at line y. The line of intersection has been remarked in red.
Answer:
Step-by-step explanation:
First write out the vector and do the computation.
After that sketch the vector on the graph the arrow show where the vector is pointing to.
You can use the vector v to find the unit vector
