Step-by-step explanation:
Confidence interval = mean ± margin of error
CI = μ ± ME
The mean is μ = 8.7.
Margin of error = critical value × standard error
ME = CV × SE
At 95% confidence and 9 degrees of freedom, CV = 2.262.
SE = s / √n
SE = 3.3 / √10
SE = 1.04
The margin of error is:
ME = 2.262 × 1.04
ME = 2.36
CI = 8.7 ± 2.36
CI = (6.34, 11.06)

Answer:
Table 3; Blue graph; y = -4; 2x-3y = 7.
Step-by-step explanation:
Table 3 is a linear relationship because the y-coordinates, or outputs, change by the same rate throughout the table. A constant rate of change defines a linear function.
The blue graph is linear because it is a straight line.
The equation y = -4 is linear because it is the equation of a horizontal line at -4. A function with a line for a graph is linear.
The equation 2x-3y = 7 is linear because it is written in standard form of a linear function, Ax+By = C (in this case A = 2, B = -3 and C = 7).
