Question

What is the slope of the line that passes through the points (5.-1) and (-3.3)? A -2 B. - C. D. 2

Answer 1

The slope of a straight line is calculated by the formula

`\begin{gathered} \text{slope}=(y_2-y_1)/(x_2-x_1) \\ \text{The two points are:} \\ (x_1,y_1)=(5,\text{ -1)} \\ (x_2,y_2)=(-3,\text{ 3)} \end{gathered}`

Hence,

`\begin{gathered} \text{slope}=(3-(-1))/(-3-5) \\ =(3+1)/(-8) \\ =(4)/(-8) \\ =-(1)/(2) \end{gathered}`

Option B is the correct
