1. first count the spaces from each intersection, starting with down. #1 has a slope of 2/3. Since it's leaning to the left, it's a negative. The only one with -2/3 is the third option down.
2. Again, look at the slope. this one is 2/1 (or just 2), and is leaning to the left, so is negative. Since there are multiple with -2 as the slope, we then look at the y-intercept. It's -1. The only answer that lines up perfectly with what we have is the third one down.
