You can put this solution on YOUR website!
You are asked to find the equation of the line in the form y+=+mx+%2Bb
You are given the slope m=-1%2F2
You are given a point that is not the y intercept (b).
So you need to find b. The point b is (0,b)
m+=+%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
-1%2F2+=+%28-6+-+b%29%2F%286+-+0%29
-3+=+-%286%2Bb%29
3+=+6+%2B+b
-3+=+b
y+=+%28-1%2F2%29x+-+3
