What is the equation of the line x - 3 y equals 18 in slope intercept form

Which approach to the theory-and-research cycle does the following sequence reflect: (1) specific observations suggest generalizations, (2) generalizations produce a tentative theory, (3) the theory is tested through the formation of hypotheses, and (4) hypotheses may provide suggestions for additional observations?

X2 + y 2 = 36 x + y = 6 solve the system of equations.

Combine the information in the problem and the chart using the average balance method to solve the problem.
