Question in CHY1205
This question aims to test understanding and ability to use the laws of indices.

Question in CHY1205
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.
