A equation of a linear function in a standard form:
Ax + By = C

<h3>Answer: YES. It's a linear function.</h3>
The equation of y in terms of x is y =(c/b) - (a/b)x
<h3>What is an Equation ?</h3>
An Equation is a mathematical statement formed when two algebraic expressions are equated with an equal sign.
The equation given in the question is
ax + by = c , b ≠ 0.
Express y in terms of x in the equation
by = c - ax
y = (c/b) - (a/b)x
Therefore the equation of y in terms of x is y =(c/b) - (a/b)x
