Quick Check:
1. C (-2)
2. C (-1)
3. A (2/3 or you could say 2 over 3)
4. B (1)
5. D (3)
These answers will give you a 5/5 100%
Remember the teachers can change the order of the questions or the questions in general, or they could change the answers.
But as of right now (1/29/2019 Tuesday), these answers are correct!

Your problems are written in a very unconventional manner which makes them difficult to read and understand. Normal format: (x,y) = (3,4), (6,7).
To find the slope of a graph or a line, you can use the formula:
slope = (change in y) / (change in x)
1. In the first graph, the change in y is 2 and the change in x is 1. So, the slope is 2/1 = 2.
2. In the second graph, the change in y is -1 and the change in x is 1. So, the slope is -1/1 = -1.
3. In the third graph, the change in y is 0 and the change in x is 1. So, the slope is 0/1 = 0.
4. In the fourth graph, the slope is undefined. This occurs when the line is vertical and there is no change in x.
To find the slope of a line going through two points, you can use the same formula:
slope = (change in y) / (change in x)
5. For the line that goes through the points (-1, -4) and (1, -7), the change in y is -7 - (-4) = -3 and the change in x is 1 - (-1) = 2. So, the slope is -3/2.
6. For the line that goes through the points (-5, 3) and (-3, -5), the change in y is -5 - 3 = -8 and the change in x is -3 - (-5) = 2. So, the slope is -8/2 = -4.
By using the formula for slope and calculating the change in y and change in x, you can find the slope for different graphs or lines.
