The cost of building an airplane with 200 seats is about $100 million. If the cost, in millions of dollars, c, is proportional to the number of seats, s, what equation can be used to determine the cost, in millions of dollars, to build an airplane with any number of seats?

On a coordinate grid, point p is at (4, 3) and point r is at (−2, −5). points q and s are a reflection of both points across the x-axis. what are the coordinates of q and s? q(−4, 3), s(2, −5) q(4, −3), s(−2, 5) q(−4, −3), s(2, 5) q(−4, 3), s(−2, 5) ; -; i can't figure it out, if someone can me with the answer,that would be nice

Could answer every question with steps
