3x + 2. Slope: 3. Y-intercept: 2
The 2 is where the line falls on the y axis it is called the y-intercept. It is 3x because you need to go up 3 left one to get to the next point on the line. It could also be known as 3/1 that simplifies to 3. This is the slope so if you just want the slope it would be 3. Think about it this way start at the 2 or the y-intercept now how many points do you need to go to get to the next point. Go up 3 and over 1 and you would get to -1, 5. Make sense?
