Straight line graph formula

A 'concept test'.  3 multiple choice questions about a graphed normal distribution curve modelling IQ data.

The diagram contains a line and a hidden glider on that line.

The JavaScript preamble adds a callback which shows the glider when the question advice is displayed.

The easiest type of exponential to graph where the base is greater than 1 and no transformations take place.

Some questions which use JSXGraph to create interactive graphics.

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.

This question uses a Geogebra applet to solve a linear program with two variables using the graphical method. It contains three steps:

1. Construct the feasible area (polygon) by adding the constraints one by one. The students can see what happens when the constraints are added.
2. Add the objective function, and the level set of the objective value is shown, as well as its (normalised) gradient.
3. Compute the optimal solution by moving the level set of the objective around.

Match the graphs to the functions. No randomisation. Multiple choice.

Match the relevant graph (sin, cos, tan) with its equation. 

Multiple choice - select the quadratic graph.

Calculating gradient and finding intercept from a geogebra graph.

Determine the correct parametric representation of a given curve.  Curve is randomly chosen from a set of 20.

The graph of the curve was not displayed on my machine.
