Question

which of the following is closest to the slope of the line of best fit shown below?
0.36
5
10
20

Explanation:

Step1: Select two points on the line of best - fit

We can choose the points approximately. Let's take the point where the line crosses the y - axis (close to (0, 0)) and another point, say (50, 18).

Step2: Use the slope formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1 = 0,y_1 = 0,x_2=50,y_2 = 18$. Then $m=\frac{18 - 0}{50 - 0}=\frac{18}{50}=0.36$.

Answer:

0.36
