Can X equals 2 be written in slope intercept form?

Answer 1

No. Slope intercept form is a way to represent linear equations, and usually, a linear function. x=2 isn't a function, as every point has the same domain value mapping to infinitely many different range values. The slope of x=2 is considered to be undefined, since using the slope formula forces you to divide by zero. Essentially, vertical lines like x=2 have infinite slopes, and therefore, it doesn't make sense to represent them in slope intercept form, especially since they don't really have a slope and only one, x=0 actually touches the y-axis (everywhere though).
