Question

Is it 1/5 or -8 trying to figure this out for the slope

Answer 1

From the graph it can be observed that line passes through points (0,16) and (2,20).

The formula for the slope of line pasing through points (x_1,y_1) and (x_2,y_2) is,

$m=\frac{y_2-y_1}{x_2-x_1}$

Determine the slope of line passing through points (0,16) and (2,20).

$\begin{gathered} m=\frac{20-16}{2-0} \\ =\frac{4}{2} \\ =2 \end{gathered}$

So slope of line is 2.
