I’m pretty sure it’s y=-4x-16

Because the standard slope equation is y=mx+b and in perpendicular lines the slope is opposite of the slope on a parallel line. 0.25 is equal to 1/4 and the opposite of 1/4 is 4/1 but you also make it negative so it’s -4. So we have y=-4x+b and you plug in the coordinates and solve [8=-4(-6)+b and -4*-6=24 so you rewrite it as 8=24+b and 8-24=-16 and -16=b] so you plug in b and the equation is y=-4x-16

Hope this helped

Answer:

<em>The polygon area is </em> $51.5 U^{2}$ <em />

Step-by-step explanation:

Points:

(2,7), (8,2), (6,11), (6,5), (11,6)

1. The area of the polygon could be calculate with the eqation:

$A=\frac{1}{2}\left[\begin{array}{ccc}x_{1} &y_{1}\\x_{2} &y_{2}\\x_{3} &y_{3}\\x_{4} &y_{4}\\x_{5} &y_{5}\end{array}\right]$

2. Replace the coordinates in equation for A:

$A=\frac{1}{2}\left[\begin{array}{ccc}2&7}\\8&2\\6&11\\6&5\\11&6\end{array}\right]$

3. Solve the determinant, and calculate A:

$A=\frac{1}{2}\left[\begin{array}{ccc}2&7}\\8&2\\6&11\\6&5\\11&6\end{array}\right]\\A=\frac{1}{2}[(6)(7)+(11)(11)+(8)(6)+(6)(2)]-[(2)(11)+(6)(6)+(11)(2)+(8)(5)]\\A=\frac{1}{2}[42+121+48+12]-[22+36+22+40]\\A=\frac{1}{2}[223]-[120]\\\\A=\frac{1}{2}[103]=51,5 U^{2}$

<em>The polygon area is </em> $51.5 U^{2}$ <em />
