Changing x to 2D so as to make a linear regression plot

Question

    SAT GPA
0   1714    2.40
1   1664    2.52
2   1760    2.54
3   1685    2.74
4   1693    2.83

The above is the first 5 rows of my data set, however i want make a simple linear regression model of SAT score against GPA. i tried changing my independent variable(SAT) to 2D with the format below but i got an error message saying "series object has no attribute 'reshape'". kindly help pls

y=data.GPA
x=data.SAT.reshape([-1, 1])
