Answer:
r=-3
Step-by-step explanation:
-----(A)
Here we are given that
![(x_1,y_1) = (2,r)](https://tex.z-dn.net/?f=%20%28x_1%2Cy_1%29%20%3D%20%282%2Cr%29%20)
![(x_2,y_2) = (-5,11)](https://tex.z-dn.net/?f=%20%28x_2%2Cy_2%29%20%3D%20%28-5%2C11%29%20)
And the value of m is -2
Replacing them in (A)
![-2=\frac{11-r}{-5-2}](https://tex.z-dn.net/?f=%20-2%3D%5Cfrac%7B11-r%7D%7B-5-2%7D)
![-2=\frac{11-r}{-7}](https://tex.z-dn.net/?f=%20-2%3D%5Cfrac%7B11-r%7D%7B-7%7D)
![-7 \times -2=11-r](https://tex.z-dn.net/?f=%20-7%20%5Ctimes%20-2%3D11-r)
![14=11-r](https://tex.z-dn.net/?f=%2014%3D11-r)
![r=11-14](https://tex.z-dn.net/?f=%20r%3D11-14)
![r=-3](https://tex.z-dn.net/?f=%20r%3D-3)
Hence the value of r is -3 and the coordinate is(2,-3)
