There are copious comments in the definition of the function eqnline about the voodoo needed to have a JSXGraph diagram interact with the input box for a part.

Use two points on a line graph to calculate the gradient and $y$-intercept and hence the equation of the straight line running through both points.

The answer box for the third part plots the function which allows the student to check their answer against the graph before submitting.

This particular example has a positive gradient.

Given the graphs of two functions $f$ and $g$ can you sketch the graph of $f+g$?

Yr 7 Simple Linear Equations, integer answers only

Given a table of data, complete a frequency distribution table and use it to calculate the mean, mode, median and range.

Some questions of relevance to consumers.

Calculate the interest accrued in a savings account, given the initial balance and annual interest rate.

Estimate whether you can afford an extra item in a shop by rounding prices to the nearest 10p.

Find the original price before a discount by dividing the new price by the percentage discount.

Calculate a rate of pay (in pounds per week) given the total pay over a given period of time.

Eight expressions, of increasing complexity. The student must simplify them by expanding brackets and collecting like terms.

This question tests the student's ability to solve simple linear equations by elimination. Part a) involves only having to manipulate one equation in order to solve, and part b) involves having to manipulate both equations in order to solve.
