First of all, I am NEW at this! And I’m trying to learn how to make self-graded tests.
I have this question where I would like students to place a point on the graph at the solution to the system. I am now stuck. I have a draggable point and I have a correct function, but no matter where the point is dragged to, it gives the check mark. How do I fix this? Or is there a better way I could be doing this?
A couple of things:
- You probably should put a “step” on the values of a1 and b1 to make it easier to get an exact answer. Some suitable value (such as 0.5)
- You might also want to add the label of the point so a student can see how “exact” their answer is.
- Your “correctness” did not take into account the student’s coordinate point.
Take a look at this reworked solution:
Thank you so much! I thought there was something I was missing.
