identify parallel lines
QuestionStudents are given the equations of two lines in the form y=mx+b and asked if they are parallel.
The line equations are randomised.
The answer is yes or no. There is a 1 in 6 chance of the lines being parallel.

Show the student a plot of their function
QuestionThis question shows how to use the JSXGraph extension to show the student a plot of a function that they enter.
In the first part, the student enters an expression for $f(x)$. Once they've done that, they can reveal a plot of the function.

Create a JSXGraph diagram using JessieCode: Three triangle centres lie on a line
QuestionThis question demonstrates how to construct a JSXGraph diagram using JessieCode.
The construction shows a triangle and its orthocentre, circumcentre and centroid. They are always collinear. You can move the vertices of the triangle.
