Question $4$ options:

Y$-$hat equals beta sub zero plus beta sub one times x sub one plus beta sub two times x sub two plus dot dot dot plus beta sub n times x sub n$.$

Beta sub one times x sub one equals y$-$hat plus beta sub zero plus beta sub two times x sub two plus dot dot dot plus beta sub n times x sub n$.$

Y$-$hat equals beta sub zero plus beta sub one times x sub one.

Beta sub one times x sub one equals y$-$hat.
