The slope of the line is - 2<br> O True<br> O False

aniked [119]

Answer:

<h2><u>FALSE</u></h2>

Step-by-step explanation:

To find the slope you need to pick two points. Points (2,4) and (4,3) are the points I used. (It does not really matter what points you chose). Now we have to follow the formula to find the slope. The formula can be seen below

Slope (m) = ΔY/ΔX

Now solve

ΔX = 4 – 2 = 2

ΔY = 3 – 4 = -1

Once you have solved it, you take it and make it a fraction

-1/2 = -0.5

Which expression represents the greatest common factor (GCF) of 70 and 112? A. 2 x 2 x 2 x 7 B. 2 x 2 x 2 x 5 C. 2 x 7 D. 2 x 2

Mekhanik [1.2K]

Answer:

$\huge\boxed{C. \ \ GCF = 2 * 7}$

Step-by-step explanation:

<u>Firstly, we'll do prime factorization of these numbers.</u>

70 = 2 × 5 × 7

112 = 2 × 2 × 2 × 2 × 7

<u>So, The Greatest Common Factor can be written as:</u>

GCF = 2 × 7 <u>[Since Only one 2 and one 7 is common]</u>

<u></u>

Hope this helped!
