1. Which can be the intersection of three distinct planes?
a point? a line? a plane? or a ray?
2. Which line is parallel to y=3x-2
y=1 3rdx+5? y=3? y=-3x+1 or y=-one 3rdx-4?
3.What are the coordinates of the midpoint of segement CD with endpoints C(5,3) and D(0,-7)?
(2.5,-2)? (0,-2)? (-2.5,-2)? or (-3,4)?
4. Triangle ABC is obtuse. Two verticles of the triangle are A(3,4) and B(-1,1) what could be the coordinates of point C?
(-1,-3)? (3,1)? (0,0)? or (-1,4)?
a point? a line? a plane? or a ray?

A point or a line can be the intersection of three distinct planes, but a ray or a plane cannot.

None of those are parallel to y = 3x - 2. For the second possible answer, did you mean y = 3, or y = 3x? If you meant y = 3x, then that is parallel to y = 3x - 2. Only lines of the form "y = 3x", optionally plus or minus anything, are parallel to y = 3x - 2.

((5 + 0) / 2, (3 + (-7)) / 2)
The midpoint of CD is (5/2, -2).

(-1, -3). This causes angle B to be obtuse.
