a)

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

y+-+y%5B1%5D+=+%281%2F5%29%28x+-+x%5B1%5D%29 Plug in the given slope

y+-+2+=+%281%2F5%29%28x+-+3%29 Plug in the given point the line goes through

and you're done with part a)

a)

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

y+-+y%5B1%5D+=+-2%28x+-+x%5B1%5D%29 Plug in the given slope

y+-+1+=+-2%28x+-+%28-12%29%29 Plug in the given point the line goes through

y+-+1+=+-2%28x+%2B+12%29 Simplify

and you're done with part b)
