Answer:
Question 1) 2/3
Question 2) -3
Step-by-step explanation:
Question 1)
The formula of a slope is (increase in y)/(increase in x), so in the graph, all we need to do is find two precise points and look at the distance difference.
1. The two points that I've found were (0,3) and (3,5). The change in y is 3 --> 5, which is 2. The change in x is 0 --> 3, which is 3.
2. The slope will be 2/3.
Question 2)
In this question, we can consider n as x and f(n) as y.
1. The two points I chose were (4, -31) and (7,-40). The change in y is -31 --> -40, which is -9. The change in x is 4 --> 7, which is 3.
2. The slope will be -9/3.
3. -9/3 can be simplified to -3 since we can divide both the numerator and the denominator by 3.
4. The final slope will be -3.
