Hi,

these types of problems ALL follow the same method for solution:

Pts(x,y)

 (9, 1)and 

(-6,-8)      m = 9/15 = 3/5     m+=%28y%5B2%5D+-+y%5B1%5D%29%2F%28x%5B2%5D+-+x%5B1%5D%29

y+-+y%5B1%5D+=+m%28x+-+x%5B1%5D%29

y+-+1=+%283%2F5%29%28x+-9%29    |Use 1st of Points given

y+%2B+8+=+%283%2F5%29%28x+%2B6%29     |Use 2nd of Points given
