The quickest way to find the factors of a number is to divide it by the smallest prime number( bigger than 1) that goes into it evenly with no reminder. Continue this process with each number you get, UNTIL YOUR REACH 1. I hope it helps :) Let me know
Factors are numbers you can multiply to get each number. For example, for 30 you would have factors of 1, 2, 3, 5, 6, 10, 15, and 30. I got that because 1 x 30 = 30, 2 x 15=30, 3 x 10 = 30, and 5 x 6= 30. If the factors are just 1 and that number it is prime. If there are other factors, it is composite. 30 would be composite.
The rate of change would be 7. you would plot your first point on the graph at (-2,0) and the next one would be up 7 and over 1 for your next plot point.
