Identify the slope and the point used to write the equation. Write the point as an ordered pair. y − 5 = − 3 ( x + 2 )

Slope: -3

Ordered pair: (-2,5)

Step-by-step explanation:

The equation is written in point-slope form which is y-y1=m(x-x1), where y1 and x1 are the x and y coordinates and m is the slope.

Slope: -3

X = -2

Y= 5

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
