Question

use the graph to answer the questions.
(a) how much does the distance increase for each hour since iwan crossed the bridge?
(square) miles
(b) what is the slope of the line?
(square)

Explanation:

Step1: Identify graph coordinates

From the graph, at $t=0$, $d=0$; at $t=4$, $d=200$.

Step2: Calculate hourly distance increase

$\frac{200 - 0}{4 - 0} = 50$ miles/hour

Step3: Calculate slope of the line

Slope = $\frac{\text{Change in } y}{\text{Change in } x} = \frac{200 - 0}{4 - 0} = 50$

Answer:

(a) 50 miles
(b) 50
