<u>Answer:</u>

The point-slope form of the line that passes through (5,5) and is perpendicular to a line with a slope of \frac{1}{4} is 4x + y -25 = 0

<u>Solution:</u>

The point slope form of the line that passes through the points \left(x_{1} y_{1}\right) and perpendicular to the line with a slope of “m” is given as  

\bold{y-y_{1}=-\frac{1}{m}\left(x-x_{1}\right)} ---- eqn 1

Where “m” is the slope of the line. x_{1} \text { and } y_{1} are the points that passes through the line.

From question, given that slope “m” = \frac{1}{4}

Given that the line passes through the points (5,5).Hence we get

x_{1}=5 ; y_{1}=5

By substituting the values in eqn 1 , we get the point slope form of the line which is perpendicular to the line having slope \frac{1}{4}can be found out.

y - 5 = -4(x - 5)

y - 5 = -4x + 20

on simplifying the above equation, we get

y - 5 + 4x -20 = 0

4x + y - 25 = 0

hence the point slope form of given line is 4x + y - 25 = 0

What is the quadratic regression equation for the data set? ​ ​ ​ <br><br> PLEASEE HELP ME
Soloha48 [4]
You're trying to find constants a_0,a_1,a_2 such that \hat y=a_0+a_1\hat x+a_2{\hat x}^2. Equivalently, you're looking for the least-square solution to the following matrix equation.


\underbrace{\begin{bmatrix}1&6&6^2\\1&3&3^2\\\vdots&\vdots&\vdots\\1&9&9^2\end{bmatrix}}_{\mathbf A}\underbrace{\begin{bmatrix}a_0\\a_1\\a_2\end{bmatrix}}_{\mathbf x}=\underbrace{\begin{bmatrix}100\\110\\\vdots\\70\end{bmatrix}}_{\mathbf b}

To solve \mathbf{Ax}=\mathbf b, multiply both sides by the transpose of \mathbf A, which introduces an invertible square matrix on the LHS.

\mathbf{Ax}=\mathbf b\implies\mathbf A^\top\mathbf{Ax}=\mathbf A^\top\mathbf b\implies\mathbf x=(\mathbf A^\top\mathbf A)^{-1}\mathbf A^\top\mathbf b

Computing this, you'd find that

\mathbf x=\begin{bmatrix}a_0\\a_1\\a_2\end{bmatrix}\approx\begin{bmatrix}121.119\\-3.786\\-0.175\end{bmatrix}

which means the first choice is correct.
