Question

Select the correct equation.Identify the equation that represents the line of best fit on this scatter plot.

Answer 1

From the scatter plot we can conclude that the slope of the line is positive, besides, the y-intercept is 2. We can approximate the value of the slope as follows:

$\begin{gathered} (x1,y1)=(1,2) \\ (x2,y2)=(3,4) \\ m=\frac{4-2}{3-1}=\frac{2}{2}=1 \end{gathered}$

Answer:

y = x + 2
