Answer: Parallel.
- A Parallel
- B Perpendicular
- C Intersecting at one point
- D Same line
Correct answer: A. Parallel
Explanation: Line 2: 6x + 4y = 10 → 3x + 2y = 5. Same slope (-3/2) but different intercepts. Parallel.
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.
