Answer:

<h2>slope = 4</h2>

Step-by-step explanation:

The formula of a slope:

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

We have the points (9, 10) and (7, 2).

Substitute:

$m=\dfrac{2-10}{7-9}=\dfrac{-8}{-2}=4$

What is the length of the hypotenuse of the triangle below?

liberstina [14]

Answer:

$\boxed{B. Hypotenuse = 10}$

Step-by-step explanation:

By applying <em>Pythagoras theorem</em> we can find hypotenuse of a right angle triangle.

Side of right angle triangle (a) = 5√2 cm

Side of right angle triangle (b) = 5√2 cm

Hypotenuse² = a² × b²

${Hypotenuse}^{2} = {(5 \sqrt{2} )}^{2} \times {(5 \sqrt{2} )}^{2} \\ \\ {Hypotenuse}^{2} = (25 \times 2) + (25 \times 2)\\ \\ {Hypotenuse}^{2} = 50 + 50\\ \\ {Hypotenuse}^{2} = 100\\ \\ {Hypotenuse}^{ \cancel{2}} = {10}^{ \cancel{2}} \\ \\ Hypotenuse = 10$
