Rewrite y = 9x + 7 into standard form. pleas !

Np4=12np2 with clear explanation.

Determine whether the points (–3,–6) and (2,–8) are in the solution set of the system of inequalities below. x ? –3 y < 5? 3x + 2 a. the point (–3,–6) is not in the solution set, and the point (2,–8) is in the solution set. b. neither of the points is in the solution set. c. the point (–3,–6) is in the solution set, and the point (2,–8) is not in the solution set. d. both points are in the solution set.

Solve x+3y=6 and 4x-6y=6 by elimination . show work !
