Quandaries & Queries

Question from Warren, a teacher:

What are the conditions of the numerical coefficients of the standard form Ax+By=C in Linear Function?
How will you transform y=square root of 3 x + 1 in standard form Ax+By=C?

Warren,

A linear function is one that can be written in the form Ax + By = C where A, B and C are any real numbers. The term linear comes from the fact that its graph is a straight line. The graph of y = √(3x + 1) is not a straight line

y = sqrt(3x + 1)

y = √(3x + 1)

and hence the expression y = √(3x + 1) can not be written in the standard form Ax + By = C where A, B and C are real numbers.
