A line passes through the points (2, 3) and (6, 11). What is its gradient?

AIt is 2
BIt is 4
CIt is 8
DIt is 3
Answer & Solution
Correct answer: A. It is 2
1. Gradient is the ratio of vertical change to horizontal change. 2. The vertical change is 11 minus 3, which is 8. 3. The horizontal change is 6 minus 2, which is 4. 4. Dividing 8 by 4 gives a gradient of 2. 5. Answering 8 stops at the vertical change and never divides by the horizontal change. _Source: Siyavula Mathematics Grade 11 (Everything Maths, CC BY 4.0), Chapter 4: Analytical geometry_
