Question
notation check: find the gradient of the line through (21, 22) and (25, 26). Show your working one step at a time.
Answer
The final answer is 1. Gradient means change in y divided by change in x. The change in y is 4. The change in x is 4. Divide the change in y by the change in x. 1
Explanation
exam warm-up keeps the canonical answer 1 fixed before the model answer is written, so the worked solution and final answer agree.
Common mistake
Gradients and areas under graphs common mistake 1
Writing a final answer without showing the method that justifies it. This can weaken answers for: [Higher only] Interpret gradients and areas in contexts such as distance-time, velocity-time and financial graphs..
Show the method first, then give the final answer in the required form. Apply this directly to Gradients and areas under graphs.
