A principal measures the weight of different numbers of textbooks that he finds in a storage room. The scatter plot below shows

Ahat [919]

The slope of the line of best fit is 2.4

Explanation:

To determine the slope of the equation, let us plot the coordinates in the slope form.

Analyzing the graph,some of the points that are on the straight line is (5,12) and (10,24)

Let us use the points (5,12) and (10,24) to find the slope of the line of best fit.

The formula for slope is

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substituting the coordinates (5,12) and (10,24), we have,

$m=\frac{24-12}{10-5}$

Subtracting, we get,

$m=\frac{12}{5}$

Dividing, we have,

$m=2.4$

Hence, The slope of the line of best fit is 2.4
