Find the slope of the line through each pair of points.
1) (13, -11), (3, 1)
2) (4, 12), (11, 14)
3) (-8, -1), (13, 1)
4) (7.-9), (0, 2)

1.  Slope=12/-10

2. Slope= 2/7

3. Slope= 2/21

4. Slope= 11/-7

Step-by-step explanation:

to find slope, plug in the numbers for y₂-y₁ over x₂-x₁ or  y₂-y₁/x₂-x₁  this means using the y coordinate from the second point and subtracting it from the first y coordinate and keeping it in fraction form. Then you subtract the fist x value from the second x value the same way as the y. then simplify all the numbers, sometimes there are negatives but that it perfectly fine. :) I hope this helped!!

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
