Which answer is an equation in point-slope form for the given point and slope? Point: (5, 9); Slope: 2
y-5= 2 (2 +9)
y-9=2(x+5)
y+9= 2(2-5)
y-9=2(x – 5)

 y-9=2(x-5)

Step-by-step explanation: The point (5,9) satisfies the equation:

y-9=2(x-5)  for (5,9)?

9-9=2(5-5) ?

0 = 0  YES

Slope of 2?  Rewrite:  

y-9=2(x-5)

y = 2(x-5)+9

The slope is 2  YES

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
