Answer: 4
Explanation:
Ok, I know this is confusing but just bear with me,
You do not pick the 2 points on the line, you pick a number that is intersecting on the x axis. I chose 4. The 2 intercepts I got were -2,4. From -2, I went up 4 and right 1 which gives you a result of 4/1which equals 4
Hope you got the right answer :)
