Hello,
The question states:
As we will later be acting on the coordinate axes with passive transformations, we will need to have our axes stored in arrays. We can represent the x-axis as two arrays: one containing the x-values ranging from, say, -1 to 1 (you can take 100 equally spaced values) and another containing the y-values (of the x-axis), which are all 0. In a code cell, introduce two NumPy arrays for the x and y values of the x-axis,and similarly two more NumPy arrays for the x and y values of the y-axis. Type code to create a figure of appropriate size (i.e. large enough to look good) and plot the two axes as blue lines. Plot a point with coordinates (x; y) = (0:5; 0:4) as a blue circle.
