💡 Exam Tips for y = mx + c
- Check signs carefully: Is it +c or -c? Is m positive or negative?
- Read intercepts accurately: Use the grid lines to find exact values
- Show gradient calculations: Always write out the rise/run fraction
- Verify your answer: Substitute a point from the line into your equation
- Label your answer clearly: Write "The equation is y = ..."
- Use fractions when necessary: Don't always convert to decimals
