1. The vertical change from point A to point B is 1
2. The horizontal change from point A to point B is 2
3. The rate of change shown in the graph is 0.5
How to calculate the vertical, horizontal and rate of change?
1. The vertical change from point A to point B can be calculated as follow:
- Vertical value from A = 1
- Vertical value from B = 2
- Vertical change =?
Vertical change = Vertical value from B - Vertical value from A
= 2 - 1
= 1
2. The horizontal change from point A to point B can be calculated as follow:
- Horizontal value from A = 2
- Horizontal value from B = 4
- Horizontal change =?
Horizontal change = Horizontal value from B - Horizontal value from A
= 4 - 2
= 2
3. The rate of change shown in the graph can be calculated as follow:
- Vertical change = 1
- Horizontal change = 2
- Rate of change =?
Rate of change = Vertical change / Horizontal change
= 1 / 2
= 0.5
