Solve the problem.The following data represents the height (in inches) and weight (in pounds) of 9 randomly selected adults. 
Graph the data on a scatter diagram treating height as the independent variable. Find an equation of the line containing the points (62, 126) and (70, 180). Express the relationship using function notation. Graph the line on the scatter diagram. Interpret the slope of the line. Use the line to predict the weight of a person who is 64.6 inches tall. Round to the nearest pound.

Complete the square and write the equation in standard form. Then give the center and radius of the circle.x2 + y2 - 12x - 10y = -12
A. (x - 6)2 + (y - 5)2 = 49 (6, 5), r = 7 B. (x - 6)2 + (y - 5)2 = 49 (-6, -5), r = 49 C. (x - 5)2 + (y - 6)2 = 49 (5, 6), r = 7 D. (x - 5)2 + (y - 6)2 = 49 (-5, -6), r = 49
