Question

Plss I need answer fast!!

Answer 1

Answer:

C.

Step-by-step explanation:

The equation for the slope of a line is y2-y1/x2-x1, and both triangles have the same slope equation for their hypotenuse.

Answer 2

Answer:

$\huge\boxed{C.\ \dfrac{1-7}{9-5}=\dfrac{1-10}{9-3}}$

Step-by-step explanation:

$slope=\dfrac{y_2-y_1}{x_2-x_1}$

$C(9;\ 1)\\E(5;\ 7)\\B(3;\ 10)\\\\slope_{EC}=\dfrac{1-7}{9-5}=slope_{CE}\\\\slope_{BC}=\dfrac{1-10}{9-3}=slope_{CB}$
