Can someone help me find the slope?
kipiarov [429]

Answer:

Undefined

Step-by-step explanation:

First, take 2 points from the table given, then you use the equation y2-y1/x2-x1 to find your slope. So, if I take the coordinates (7,1) and (7,2) and plug them into my equation, I would get 2-1/7-7. If you solve this equation, you will end up wil 1/0. Now, if you have something like this as your answer, you can not find your slope. There can not be a slope because the zero is at the bottom, making this "Undefined".

He solution is n = –2 verified as a solution to the equation 1.4n + 2 = 2n + 3.2. What is the last line of the justification?
Nimfa-mama [501]

Answer:

-0.8=-0.8

Step-by-step explanation:

We have been given that n=-2 verified as a solution to the equation 1.4n+2=2n+3.2.

As n=-2 is the solution for our given equation, so it will satisfy our equation.

Let us substitute n=-2 is our given equation.

1.4*-2+2=2*-2+3.2

-2.8+2=-4+3.2

-0.8=-0.8

Since the value of n satisfies our equation, therefore, last line of the justification will be -0.8=-0.8.
