Знайдіть довжину відрізка \( A C \), якщо \( A(4 ;-3 ; 1), C(8 ; 1 ; 3) \). \( \begin{array}{llll}\text { А } 36 & \text { Б } 2 \sqrt{6} & \text { В } 6 & \text { Г } 4 \sqrt{6}\end{array} \)

Draw a graph of the line that contains the given point and has the given slope. \( (0,1) ; m=-3 \)

Graph the line containing the point \( P \) and having slope \( m \). \( P=(-6,3) ; m=0 \)

The midpoint between two points is \( \{1,5\rangle \). One of those points is \( \{8,3\rangle \), find the other.

coordinate grid below. Find the coordinates of a fourth point o that the four points form the vertice of a rectangle.

5. Em um polígono, a razão entre a soma das medidas dos ângulos internos e a soma das medidas dos ângulos externos é igual a \( \frac{7}{2} \). Quantos lados tem esse polígono?
