Extract point coordinates from a Table

Questions
1

I want the student to enter the Y-intersect point in a table in math mode:
( x-val, y-val)
How can I extract the student input in order to evaluate and compare with the correct answer ?

Thanks

You could use parseOrderedPair to extract the student’s x and y coordinates.

studentPoint = parseOrderedPair(this.cellContent(1,1))

xCoordinate = numericValue(studentPoint.x)
yCoordinate = numericValue(studentPoint.y)
3 
xCoordinate = numericValue(parseOrderedPair(this.cellContent(1,1)).x)
yCoordinate = numericValue(parseOrderedPair(this.cellContent(1,1)).y)
