    E If x is to a power that is not 1, the equasion is not a line. A. is a horizontal line B. is a vertical line C. is a line of slope=1 D. is a line of slope=3/4 E. is a PARABOLA. "x^2" is a giveaway sign of a parabolic function Therefore, the answer is E

    Also: A linear equation is 1st degree. Answer choice 'E' is the only equation that is not 1st degree.

    wait, wouldn't a parabola still be a line, just not a straight one?

    line means straight line in the land of math :) no parabola is not a considered a line. it is a path, or curve, but not a line.
