After the enhanced content guidance was released for Edexcel Further Maths, I saw that the equation of the line of intersection is required. I could find very few questions for this and didn’t want to spent a long time writing some, so I wrote a generator in HTML and JavaScript to generate questions (guaranteed to have integer solutions), as well as provide a worked solution. I then wrote another one to find the reflection of a point in a plane. You can find both of these on my further maths resources page.
