Answer:
there are several ways to write, and find slope...see explanation
Explanation:
Way 1: slope Intercept- y=mx+b
step 1: find where the line crosses the Y axis(the one running up and down...thats is your "b" so if the line crosses at -2...it would be this: y=mx-2
Step 2:from the point where the line crosses the Y axis, count how many up/down and Left/right to the next point..so if you go up 2 right 1, it would look like this y=2x-2
Up=positive
down=negative
left=negative
right=positive
