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 intercepts common mistake 1
Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Identify and interpret gradients and intercepts of linear functions graphically and algebraically..
Show the method first, then give the final answer in the required form. Apply this directly to Gradients and intercepts.
