Best ResponseYou've already chosen the best response.0if the equation is \[\Large \sin(2)*x  y = 14\] then you are correct the sin(2) part is a number, approx 0.034899 so the equation is approximately equivalent to 0.034899x  y = 14. You can place it into y = mx+b form

Best ResponseYou've already chosen the best response.0Okay thank you, I also had another question. Why is 2sinxy=14 non linear?

Best ResponseYou've already chosen the best response.0because of the sin(x) term if you solve for y, you get y = 2sin(x)  14 which graphs a curvy/wavy like equation and NOT a straight line. https://www.desmos.com/calculator/6xg8ycssnj

Best ResponseYou've already chosen the best response.0the big difference is what goes inside the sine function if it's a single number that doesn't change, then you can replace the sine expression with some fixed number that doesn't change but if x or some algebraic expression is inside the sine function, then you'll get that curve and pattern
