Sample Questions

1multiple choice

Find the slope of the line passing through points (2, 3) and (5, 9).

Show answer

2

Slope m = (y₂-y₁)/(x₂-x₁) = (9-3)/(5-2) = 6/3 = 2. The line rises 6 units for every 3 units horizontally. Common mistake: reversing the numerator and denominator.

2multiple correct

Which of the following points lie on the line segment joining A(1, 2) and B(5, 6)? (Select all correct answers)

Show answer

(2, 3), (3, 4), (4, 5)

Points on line AB have slope = (6-2)/(5-1) = 1. Check each: (2,3): slope from A = (3-2)/(2-1) = 1 ✓; (3,4): slope = (4-2)/(3-1) = 1 ✓; (4,5): slope = (5-2)/(4-1) = 1 ✓; (2,4): slope = (4-2)/(2-1) = 2 ✗; (6,8): outside segment range.

3multiple choice

The centroid of triangle with vertices (3, 4), (7, 8), and (5, 2) is:

Show answer

(5, 14/3)

Centroid = ((x₁+x₂+x₃)/3, (y₁+y₂+y₃)/3) = ((3+7+5)/3, (4+8+2)/3) = (15/3, 14/3) = (5, 14/3). Common mistake: not dividing by 3 or making arithmetic errors.

4multiple choice

If three points A(1, 2), B(3, 6), and C(k, 10) are collinear, find the value of k.

Show answer

5

For collinear points, slopes between any two pairs must be equal. Slope AB = (6-2)/(3-1) = 4/2 = 2. Slope BC = (10-6)/(k-3) = 4/(k-3). Setting equal: 2 = 4/(k-3), so 2(k-3) = 4, 2k-6 = 4, 2k = 10, k = 5.
