question 16

Multiple Choice

Solve the problem.
-Data points: (5, -3) , (2, 2) , (4, 3) , (5, 1) $$\mathrm { X } = \left[ \begin{array} { l l } 1 & 5 \\1 & 2 \\1 & 4 \\1 & 5\end{array} \right] , \mathrm { y } = \left[ \begin{array} { r } - 3 \\2 \\3 \\1\end{array} \right]$$

• A) \(y = \frac { 19 } { 4 } - \frac { 8 } { 3 } x\)
• B) \(y = \frac { 19 } { 4 } + \frac { 1 } { 3 } x\)
• C) \(y = \frac { 19 } { 4 } - 1 x\)
• D) \(y = \frac { 67 } { 6 } - 2 x\)
