Question

the graph represents one side of the roof of a building. the slope of the line is

Explanation:

Step1: Identify two points

Let the two points be $(2,7)$ and $(4,14)$.

Step2: Use slope - formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1 = 2,y_1=7,x_2 = 4,y_2 = 14$. Then $m=\frac{14 - 7}{4 - 2}$.

Step3: Calculate the slope

$m=\frac{7}{2}=3.5$.

Answer:

$3.5$
