after u have drawn the graph
there is likely to be 1 point which is located far away from the line that u draw
that point is the error
using the corresponding x value of that particular point , u can use the line to find out which vertical value is actually correct
let’s say the vertical value u see is “5”
and corresponding x value = 3
then y/x^2 = 5
then y/3^2 = 5
then can find y
