Worked practice questions
What are the coordinates of the origin?
- (1, 0)
- (0, 1)
- (1, 1)
- (0, 0)
Show answer and solution
Correct answer: D. (0, 0)
The origin is the intersection of the two axes: x = 0 and y = 0, so the coordinates are (0, 0).
Are the points A(1, 1), B(2, 3), C(3, 5) collinear?
- Yes
- Cannot tell
- No
- Only if rotated
Show answer and solution
Correct answer: A. Yes
AB = √(1+4) = √5. BC = √5. AC = √(4+16) = √20 = 2√5 = AB + BC.
The three are collinear.
