Hi,

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

Pts(x,y)

(12,6)

( 4,4)    m = 2/8  = 1/4    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+-+6+=+%281%2F4%29%28x+-12%29    |Use 1st of Points given

y+-+4+=+%281%2F4%29%28x+-4%29     |Use 2nd of Points given

You will have the fun of plugging those numbers in to see which ones work. Better you than me. After all it is your homework not mine.
Remember just because one point works doesn't mean that both points are on the line.
or you can find the equation from the points.
I came u[p with
y = x/4+3
