Question

What is the slope of the line that passes through the points (4,8) and (2, 12) ? Write your answer in the simplest form.

Answer 1

The slope of a line is;

`m=(y_2-y_1)/(x_2-x_1)`

Given the points;

`\begin{gathered} (4,8),(2,12) \\ x_1=4,y_1=8,x_2=2,y_2=12 \end{gathered}`

Then, the slope of the line that passes through the points is;

`\begin{gathered} m=(12-8)/(2-4) \\ m=(4)/(-2) \\ m=-2 \end{gathered}`

Hence, the slope m, is;

`m=-2`
