list the ordered pair in relation R from A= {1,3,5,7} to B = {0,1,2,6} where (a, b) E(belongs to)R (relation) if and only if a=b and. a+b=6

Do not comment if you aren’t going to . create a real-life situation and create a system and show how it might be modeled algebraically with a system of equations (or inequalities) show all work include a few sentences explaining the situation, your variables of choice and what each represents, and how you would set it up and solve it algebraically. !

Can someone answer this question? : )

One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)
