Question

this week, the price of stock ddd is $18 for each share. for the past several weeks it has been increasing and may continue. the graph models the price of each share per week. what is the slope of the line? m = question help: video

Explanation:

Step1: Select two points on the line

Let's take two points $(0, 18)$ and $(10, 28)$.

Step2: Use the slope - formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1 = 0,y_1 = 18,x_2=10,y_2 = 28$. Then $m=\frac{28 - 18}{10 - 0}$.

Step3: Calculate the slope

$m=\frac{10}{10}=1$.

Answer:

$1$
