There is an easy way to find y intercept. I can tell you how and show you the answer
1 {Y Intercept = 3 } [ This is where the line crosses the line going from up to down in the middle. ]
{slope = 2/1 } To find the slope you find a place where the slanted line is perfectly on the graph.:
You then go up. { GO UP FIRST! that will be the number on top. Stop when you notice the slanted line to the right is exactly on the graph. So what i did is started at (-1, 1) Then went up twice. I saw that to the right of me was the slanted line which was exactly on the graph. So I went up twice [2] then went right once [1]
To find your equation you just put y= [ y intercept form ] and your numbers you found.
y=2/1x + 3
Make sure you have x after your slope so you know it is always going up, no matter what number you put inside.
IF YOU WANT ME TO DO THEM ALL COMMENT. I WILL DO THEM ALL WITHOUT EXPLANATION.
** NOTE ** If the line is decreasing from the left. “\”it is negative so the slope will me - you will do that for your next question
