True Or False The Slope For The Line Of Best Fit For This Scatterplot Is About 1 class=

Sagot :

Answer:

TRUE

Explanation:

We will calculate the slope of the line of best fit as shown below:

I. Pick 2 points that lie along the graph, we have:

[tex]\begin{gathered} \left(x_1,y_1\right)=\left(5,0.4\right) \\ \lparen x_2,y_2)=\left(2,2.9\right) \end{gathered}[/tex]

II. Calculate the slope using these 2 points, we have:

[tex]\begin{gathered} slope,m=\frac{y_2-y_1}{x_2-x_1} \\ slope,m=\frac{2.9-0.4}{2-5} \\ slope,m=\frac{2.5}{-3} \\ slope,m=-\frac{5}{6}\text{ or }-0.83333 \\ \\ \therefore slope,m=-\frac{5}{6}\text{ or }-0.83333 \end{gathered}[/tex]

The slope is -5/6 (which is about -1)

Hence, the answer is TRUE
