ivolga24 [154]

Answer:

Step-by-step explanation:

Let 10 be a, and 24 be b, and the undefined hypotenuse be c.

$a^2 + b^2 = c^2$

$10^2 + 24^2 = c^2$

100 + 576 = c

c = 676

$\sqrt{100} + \sqrt{576} = \sqrt{676}$

$10^2 + 24^2 = 26^2$

c = 26

The value of the undefined line is 26.

Write in point slope form of the line that passes through the points (3,-1) and (6,-2)

skelet666 [1.2K]

$\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{-1})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{-2}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-2-(-1)}{6-3}\implies \cfrac{-2+1}{3}\implies -\cfrac{1}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-1)=-\cfrac{1}{3}(x-3)\implies y+1=-\cfrac{1}{3}(x-3)$
