Answer:
B
Step-by-step explanation:
the roots are the x-values where the graph intersects the x-axis. to find the roots replace y with 0 and solve for x
The degrees of freedom for the chi square statistic is 7-4=3
The distance between the points is 8.
Y= 1/3x + 4
4 is the y intercept and it goes across one and down 3 for the get the slope of 1/3.
