Find the gradient of the line through (0, 5) and (1, 3).
Answer and explanation
Correct answer: D. -2
- Step 1: Gradient = (y2 - y1)/(x2 - x1) = (3 - 5)/(1 - 0). Step 2. = -2/1 = -2. Answer: -2. Why not the others: 2: The sign is reversed: the change in y is divided by the change in x in the same order. -1/2: That is the change in x divided by the change in y, the wrong way round. -1: That is one more than the change in y divided by the change in x.
