Question

Find the slopes of the line that goes thru the following points

Answer 1

Given:

Find-: Slope of the line.

Sol:

The slope of line is:

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

Where,

`\begin{gathered} (x_1,y_1)\text{ = First point} \\ \\ (x_2,y_2)=\text{ Second point} \end{gathered}`

Choose any point:

`\begin{gathered} (x_1,y_1)=(-1,-4) \\ \\ (x_2,y_2)=(0,-1) \end{gathered}`

So, the slope of the line is:

`\begin{gathered} m=(y_2-y_1)/(x_2-x_1) \\ \\ m=(-1-(-4))/(0-(-1)) \\ \\ m=(-1+4)/(0+1) \\ \\ m=(3)/(1) \\ \\ m=3 \end{gathered}`

Slope of line is 3.
