Question

graphs, functions, and sequences finding slope given the graph of a line in quadrant 1 that models a real-... (a) how much does the distance increase for each hour since shen crossed the bridge? miles (b) what is the slope of the line?

Explanation:

Step1: Select two points on the line

Let's take the points (0, 0) and (2, 120).

Step2: Use the slope - formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1 = 0,y_1 = 0,x_2=2,y_2 = 120$. So $m=\frac{120 - 0}{2 - 0}=\frac{120}{2}=60$.

Answer:

(a) 60 miles
(b) 60
