Answer: 3y = 5x.
- A 5y = 3x
- B 3y = 5x
- C y = 5x
- D y = 3x+5
Correct answer: B. 3y = 5x
Explanation: Slope = 5/3. Through origin: y = (5/3)x, or 3y = 5x.
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.
