Note: It seems you forgot to attach the table diagram. After a little research, I am able to find a table which is attached below.
Answer:
we conclude that:
- The y-intercept = b = -1/3
Explanation:
Finding the slope
Taking two points from the given table (check the attached diagram)
Finding the slope between (-3/4, -1/30) and (-1/2, -2/15)



Finding the y-intercept
We know that the slope-intercept form of the line equation is

where m is the slope and b is the y-intercept.
Given
substitute to find the y-intercept (b)


switch sides





Therefore, we conclude that:
- The y-intercept = b = -1/3
