Answer:
Slope of the line is 2.
Explanation:
Given coordinates of the point joining to form line are ( 3 , 9 ) and ( 1 , 3 )
We need to find Slope of line.
Slope of line from two given points are given as,
![Slope=(y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2019/formulas/mathematics/high-school/e6flxt65tbq4bgi2sypq2twajqavhlropc.png)
Required Slope of line =
![(9-3)/(3-1)=(6)/(3)=2](https://img.qammunity.org/2019/formulas/mathematics/middle-school/wyy5c0l0gd20rumbzfy85hgp6vqg5eb38l.png)
Therefore, Slope of the line is 2.
