How to create Chart like this one

T

Tim

I want to create a LINE chart that keeps track of the student progress. The
x-axis starting from 1 to upper bound, say, 10, and the y-axis is the
student scores. The LINE will starts from the second coordinate (2ndX, 2ndY)
and increasing by (x+5,y). Can you show me how to do that?
