Can a linear equation represent a function if the straight line does not cross any lines of the graph?
Answered by Reiny
not sure what you mean by "any lines of the graph", are you talking about the x or y axes ?

if a line is horizontal, then it must cross the y-axis
and all horizontal lines are functions

if a line is vertical, then it must cross the x-axis, it is NOT a function

any other straight line must cross both the x and the y axes, and it would be a function
