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 …

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, …

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.

To find y-intercept, substitute x = 0 and solve for y. a (0)+ by + c =0. 0+ by + c =0. by = -c. The y-intercept of a line ax + by + c = 0 is (0, c b) or simply c b. Finding the y-Intercept of a Line …

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 …

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 is found using the formula: y = c when x = 0 in y = mx + c. For equations not in this form, substitute x = 0 and solve for y to get the y-intercept.

What is the Y-intercept of the line pictured below?
