Search in How to Find the y-Intercept of a Line articles.
In standard form Ax + By = C, the x-intercept comes from setting y = 0 and solving for x, and the y-intercept from setting x = 0 and solving for y. Below: the method step by step, worked examples, and the sign errors that most often flip an answer.
Algebra 1 Finding the y-Intercept The y-intercept is where a line crosses the y-axis, the point where \(x = 0\). In \(y = mx + b\) it’s just \(b\); from a graph it’s where the line hits the vertical axis. We’ll find it every way, with a solver, drills, and a worksheet maker a tap […]
