hi @reetbiswas503
in this challenge we are provided with :
1.the time for a student study
2.the score he is obtaining

know using the previous traits features of student we have to predict the score of student with number of studying hours provided

so its likely to be a linear relation : as the more we study the more we get the marks

so we try to fit the data lineraly on a line using linear regression
