Hi,

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

Pts(x,y)

(-3,4) and 

( 2,1)     m = 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+-+4+=+%28-3%2F5%29x+%2B3%29    |Use 1st of Points given

y+-+1+=+%28-3%2F5%29%28x+-2%29     |Use 2nd of Points given
