Oct 27, 2025 · The equation of a line describes the relationship between the x-coordinates and y-coordinates of all points that lie on the line. It provides a way to mathematically represent that …

To check if a point lies on a line, substitute the x-value or the y-value of the point into the equation. If the other value you get matches the point’s coordinates, then the point lies on the …

Based on the equation of the line, the y-intercept is 3, meaning that the line goes crosses y-axis at the point (0, 3). The slope is 2, or 2/1, so for every 1 unit of change in y, there is a 2 units …
