Please make sure it is correct

1) linear: this equation just gives us a straight line with no curves
2) linear: this equation gives us a horizontal line
3) non linear: the -2x^2 makes the equation a parabola, so the graph is not a straight line. It looks like an upside down u. Therefore because this equation is a parabola, it is not a linear equation

Im not that good with division but i think 5 is -6but dont quote me on thatim not the best in division but thats my answer

The answer would be c
