What are you trying to prove here? I know when step will be the use of the Transitive Property. If a=b, and b=c, then a=c.

The point-slope form:

$y-y_1=m(x-x_1)$

The formula of a slope:

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

We have the points A(-2, 6) and B(2, -2). Substitute:

$m=\dfrac{-2-6}{2-(-2)}=\dfrac{-8}{4}=-2\\\\y-6=-2(x-(-2))\\\\\boxed{y-6=-2(x+2)}\to\boxed{(B)}$

What is the measure of y? (Hint- find the sum of the interior angles first)

Degger [83]

Answer:

Option A. $115\°$

Step-by-step explanation:

we know that

The sum of the interior angles in a polygon is equal to the formula

$S=(n-2)180\°$

where

n is the number of sides of polygon

In this problem we have

$n=5\ sides$

substitute the value in the formula

$S=(5-2)180\°=540\°$

$540\°=90\°+135\°+y\°+88\°+112\°$

Solve for y

$540\°=425\°+y\°$

$y=540\°-425\°=115\°$
