- B 2:1
- C 1:3
- D 3:1
Correct answer: A. 1:2
Explanation: Section formula: x = mx2/(m+n) (for internal from origin). 2 = 6m/(m+n). 2m+2n=6m, 2n=4m, m/n = 1/2. Ratio = 1:2.
The slope of a line is the ratio of vertical change (rise) to horizontal change (run) between any two points on it - equivalently, the tangent of the angle θ the line makes with the positive x-axis.
