Context. Eight students, their study hours and their test scores. A scatter plot shows whether the two move together.
Your task. Write make_scatter(hours, scores) that draws one dot per (hours, scores) pair and returns the axes.
Example. The student with 1 hour and score 52 becomes the dot at (1, 52).
Notes. Use a scatter, not a line — dots live in ax.collections, not ax.lines.
