Question

1. Which is not a linear function? A. y=+*+2 B. 2x - 3y = 12 C. Y y = -5x D. y = x

Answer 1

The general equations describing a linear function is written as

`\begin{gathered} y=mx+b \\ ax+by=c \end{gathered}`

Based on the options given, letters A and C exhibit the same formula structure with y = mx + b while letter B has the same structure as ax + by = c. This means that these equations are considered a linear function.

Letter D is not considered a linear function since it does not follow the general structure of a linear function.

Answer: D
