# Discretely increasing

Draw the graph of any linear function y(t)=a*t+b, where a and b are any numbers, at any sampling interval, and save the function values to a file.

Have a look at the sequence of values for the function and show that they form an arithmetic progression (to within rounding errors).

Relate the common difference to the values of a, b and the sampling interval used.
