What is the slope of the trend line in the scatterplot ? Show workWhat is the equation for the trend line shown in problem 11?show work

Answer 1

Given

$\begin{gathered} \text{Point 1 (12,24)} \\ Po\text{ int2(2,79)} \end{gathered}$

Using slope formula

$\begin{gathered} \text{Slope (m)=}\frac{y_2-y_1}{x_2-x_1} \\ x_1=12 \\ x_2=2 \\ y_1=24 \\ y_2=79 \end{gathered}$$\text{Slope (m)=}\frac{79-24}{2-12}=\frac{55}{-10}=-5.5$

To write the equation

$undefined$
