Here's the question you clicked on:
isabella_23
=12 is the function linear?
that is no function, it is not even a equation
not even a complete expression
its not a complete question ...........
I assume typo: y = 12 is horizontal line x = 12 is vertical line They are linear equations.
yea..............sure
does x=12 pass the vertical line test. no
any variable with an exponent greater than 1 is not a linear equation such as x^2 = 12 is not linear. just look for the highest degree (aka highest exponent
and x = 12 technically isn't a function nor does it have slope so it isn't even a "line" by mathematical standards i guess
