Work Step by Step

The slope-intercept form of the equation of non-vertical line with slope m and y-intercept b is \[y=mx+b\]. So, The equation \[Ax+By=C\] can written as: \[\begin{align} & By=-Ax+C \\ & y=-\frac{A}{B}x+\frac{C}{B} \\ \end{align}\] Here, x-coefficient is the line’s slope, \[m=-\frac{A}{B}\]. The constant term is the y-intercept, \[b=\frac{C}{B}\].
