Explanation:
We have been given coordinates of two points on a line. We are asked to find the slope of the line using given points.
We will use slope formula to solve our given problem.
, where,
m = Slope of line,
= Difference between two y-coordinates on the line.
= Difference between two x-coordinates of the same y-coordinates.
Let
and
![(-1,3)=(x_2,y_2)](https://img.qammunity.org/2020/formulas/mathematics/college/vf1d3ecxqmrr0wv30oj13suivhij14f8nv.png)
Substitute coordinates of the given points in slope formula:
![m=(3-3)/(-1-2)](https://img.qammunity.org/2020/formulas/mathematics/college/uvzn8cxn29ug85mxetakn7xscyl16yoaa5.png)
![m=(0)/(-3)](https://img.qammunity.org/2020/formulas/mathematics/college/h9ps0juq4rvz6ltp15ubp3pu7azw6gr785.png)
![m=0](https://img.qammunity.org/2020/formulas/mathematics/middle-school/gsy7o1iicsh2vmz5jn8c44p4co1jk0zqoz.png)
Since the y-coordinates of both points is same, which represents a horizontal line.
Since rise or vertical displacement is 0, therefore, the slope of the line passing through given points is 0.
