Given:
Two points are A(6,1) and B(9,4).
To find:
The equation of the line that passes through the given points.
Solution:
If a line passes through two points
and
, then the equation of the line is:
![y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%28x-x_1%29)
It is given that the line passes through the two points A(6,1) and B(9,4). So, the equation of the line is:
![y-1=\dfrac{4-1}{9-6}(x-6)](https://tex.z-dn.net/?f=y-1%3D%5Cdfrac%7B4-1%7D%7B9-6%7D%28x-6%29)
![y-1=\dfrac{3}{3}(x-6)](https://tex.z-dn.net/?f=y-1%3D%5Cdfrac%7B3%7D%7B3%7D%28x-6%29)
![y-1=1(x-6)](https://tex.z-dn.net/?f=y-1%3D1%28x-6%29)
![y-1=x-6](https://tex.z-dn.net/?f=y-1%3Dx-6)
Adding 1 on both sides, we get
![y-1+1=x-6+1](https://tex.z-dn.net/?f=y-1%2B1%3Dx-6%2B1)
![y=x-5](https://tex.z-dn.net/?f=y%3Dx-5)
Therefore, the equation of the line is
.
