What is the gradient of the line through (1, 2) and (5, 10)?
Answer and explanation
Correct answer: C. 2, because the rise of 8 is over a run of 4
Answer: 2. Why not the others: 1/2 inverts rise over run; 4 is the run alone; -2 mixes the order of the subtraction.
- Step 1: Rise: 10 - 2 = 8.
- Step 2: Run: 5 - 1 = 4.
- Step 3: Gradient: 8 / 4 = 2.
