Answer
The last option offers the most precision.
1. The point where x and y axis meet is the intersect, origin of the coordinate system (0,0)
2. m<A and m<D = 90 then <A and D are complementary angles
3. 180 angle or linear rays
4. Obtuse angle measure more than 90
5. Segment of equal lengths are congruent segments
6. Lines that meet at a 90 angle are perpendicular
2 - 2 x 3 + 3
= 2 - 6 + 3
= -4 + 3
= -1
I don’t even know the answer to be honest
