The equation Ax + By = C represents a linear equation, since both x and y have exponents 1. We can also write this equation in the slope-intercept form:
[tex]\begin{gathered} Ax+By=C \\ By=-Ax+C \\ y=-\frac{A}{B}x+\frac{C}{B} \end{gathered}[/tex]So the slope of the linear equation is -A/B and the y-intercept is C/B.
This equation cannot represent a nonlinear function, therefore the correct option is FALSE.
