The GCF stands for greatest common factor. To represent a sum by its GCF we need to use the distributive property and we need to first find the GCF of the numbers. Let's break each number by its factors:

We now multiply the numbers that appear on both.

We now apply the distributive property:

Use equation (y2-y1)/(x2-x1)
(3-(-1))/(0-5)
4/-5 is the slope
        
             
        
        
        
Answer:
0.66
Step-by-step explanation:
As division is always done before addition you would divide the 6 by 10 and then divide the 6 by 100. 6 divided by 10 is equal to 0.6 as you move the decimal point to the left once. 6 divided by 100 is equal to 0.06 as you move the decimal point to the left twice. Addition is always done after division so you would add 0.6 and 0.06 together. This will give you 0.66 as your answer.
