Question

which of the following is closest to the slope of the line of best fit shown?
a - 2.27
b - 0.44
c 0.44
d 2.27

Explanation:

Step1: Select two points on the line

Let's take \((0,0)\) and \((5,2)\) (approximate points on the line of best - fit).

Step2: Use the slope formula

The slope formula is \(m=\frac{y_2 - y_1}{x_2 - x_1}\). Here, \(x_1 = 0,y_1 = 0,x_2=5,y_2 = 2\). Then \(m=\frac{2 - 0}{5 - 0}=\frac{2}{5}=0.4\).

Answer:

C. \(0.44\)
