Question

Given the points (7, 4) and (0, -7) find the slope. Round to at least 3 decimal values if needed.

Answer 1

Formula of slope :

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

where,

$\begin{gathered} (x_1,y_1)=\text{ Point} \\ (x_2,y_2)=\text{ Point} \end{gathered}$

Points.

$\begin{gathered} (x_1,y_1)=(7,4) \\ (x_2,y_2)=(0,-7) \end{gathered}$

$\begin{gathered} x_1=7 \\ y_1=4 \\ x_2=0 \\ y_2=-7 \end{gathered}$

$\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ m=\frac{-7-4}{0-7} \\ m=\frac{-11}{-7} \\ m=\frac{11}{7} \\ m=1.571 \end{gathered}$

So slope is 1.571
