The line is x= 3.
Answer:
The equation of the least-squares regression line for this plot is approximately ŷ = 3.8 + two thirds times x.
Step-by-step explanation:
Answer: n = -198
Step-by-step explanation: To find n we need to work backwards, so we need to multiply -11 x 18 to get -198. So n would be -198.
