Oct 20, 2024 · We’ll walk you through all the major ways to find the y-intercept when you already have the slope and a point, two points, or just want to use a simple equation.

The y-intercept formula says that the y-intercept of a function y = f (x) is obtained by substituting x = 0 in it. Using this, the y-intercept of a graph is the point on the graph whose x-coordinate is 0. i.e., just …

Free how to find y intercept math topic guide, including step-by-step examples, free practice questions, teaching tips and more!

Jul 23, 2025 · When an equation isn't in the form y = mx + b, we determine the intercepts by substituting 0 as necessary and solving for the corresponding variable. To find the y-intercept, we set x = 0 and …

The slope and y-intercept formula, most commonly known as the slope-intercept form, is a linear equation containing the slope and the y-coordinate of the line's y-intercept: y = mx + b.

The slope-intercept form of the equation of the line is y = mx + b, where m is the slope and b is the y-intercept of the line. To find y-intercept, substitute x = 0 and solve for y.

Dec 12, 2025 · When the equation of a line is written in slope-intercept form (y = m x + b), the y -intercept is the constant, which is represented by the variable b. For example, in the linear equation y …

Where a line crosses the y-axis of a graph. Just find the value of y when x equals 0. In the above diagram the line crosses the y axis at y = 1.

The Y-Intercept of a line is the point where a line 's graph intersects (crosses) the Y-axis. A y-intercept of 3 means that a line's graph intersects the Y-axis at the point (0, 3).

y = c/b. This is the required y intercept formula. A y-intercept ‘c’ of a line is the value of ‘y’ at which the line crosses the y-axis. There is another equation in the form of y = mx + n, where ‘m’ is the slope of …
