Triangle ABC and triangle CDE are similar right triangles. Which proportion can be used to show that the slope of AC is equal to

Marianna [84]

Answer:

(6 - 3)/(-3 - (-1))

(3 - (-3))/(-1 - 3)= 6/(-4)

Step-by-step explanation:

Slope AC = (y(A) - y(C))/(x(A) - x(C)) = (6 - 3)/(-3 - (-1)) = 3/(-2)

Slope CE = (y(C) - y(E))/(x(C) - x(E)) = (3 - (-3))/(-1 - 3)= 6/(-4) = 3/(- 2)

Distance formula

$\boxed{\sf \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}$

Now

$\\ \tt\Rrightarrow AB=\sqrt{(3-3)^2+(-2-8)^2}=\sqrt{100}=10units$

$\\ \tt\Rrightarrow OK=\sqrt{(5-7)^2+(-2+2)^2}=\sqrt{4}=2units$

$\\ \tt\Rrightarrow LM=\sqrt{(-4-4)^2+(6+4)^2}=\sqrt{64+100}=\sqrt{164}\approx 13units$

$\\ \tt\Rrightarrow PC=\sqrt{(5-2)^2+(1-3)^2}=\sqrt{9+4}=\sqrt{13}=3.2units$

$\\ \tt\Rrightarrow QR=\sqrt{(-2+10)^2+(3-9)^2}=\sqrt{64+36}=\sqrt{100}=10units$
