Question

Which equation does NOT graph a line? A) y = 5 B) y = -3x3 C) y = 2 3 x Eliminate D) y = −8x

Answer 1

the correct answer is B

Answer 2

Letter B has a power of 3 so it is a cubic function and will not graph as a line.

y = 5 is a horizontal line
y = 23x is a line with positive slope
y = -8x is a line with negative slope
