This graph represents the linear relationship between the time in hours and Thomas's elevation in meters. For each hour, his elevation increases at a constant rate. After 3 hours, Thomas’s elevation is 1,600 meters. After 7 hours, his elevation is 3,600 meters. Let’s write an equation to represent this line in the form y=mx+b. Start by finding m, or the slope. What is the slope of this line? In other words, what is Thomas’s change in elevation for each hour?

To find the slope \( m \) of the line representing Thomas's change in elevation over time, we can use the two points provided:
- Point 1: \( (3, 1600) \)
- Point 2: \( (7, 3600) \)
The formula for the slope \( m \) is given by:
\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]
Here, \( (x_1, y_1) = (3, 1600) \) and \( (x_2, y_2) = (7, 3600) \). Plugging in the values, we get:
\[
m = \frac{3600 - 1600}{7 - 3} = \frac{2000}{4} = 500
\]
So the slope \( m \) is 500 meters per hour.
This means Thomas's elevation increases by 500 meters for each hour.
Final answer:
**Slope = 500**
- Point 1: \( (3, 1600) \)
- Point 2: \( (7, 3600) \)
The formula for the slope \( m \) is given by:
\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]
Here, \( (x_1, y_1) = (3, 1600) \) and \( (x_2, y_2) = (7, 3600) \). Plugging in the values, we get:
\[
m = \frac{3600 - 1600}{7 - 3} = \frac{2000}{4} = 500
\]
So the slope \( m \) is 500 meters per hour.
This means Thomas's elevation increases by 500 meters for each hour.
Final answer:
**Slope = 500**
