The y-intercept of a function y = f(x) is a point where its graph would meet the y-axis and is obtained by substituting x = 0. Understand the y-intercept and its formula with derivation, examples, and FAQs.
In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.
What Is Y-Intercept? The y-intercept of a graph is the point where the graph crosses the y-axis. Since the y-intercept is a point on the y-axis, its x-coordinate is always 0. Thus, the coordinates of the y-intercept are of the form (0, y). Take a look at the y-intercept of a line on a graph shown below. Note:
Oct 7, 2023 · To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y. If the equation is written in the slope-intercept form, plug in the slope and the x and y coordinates for a point on the line to solve for y.

What is the y intercept and how do you find the y-intercept? Finding the y intercept of a straight line is an important skill used to solve algebraic and real-life problems involving straight line graphs. The intercepts of a graph are where the graph crosses the coordinate axes.
What are intercepts? The x -intercept is the point where a line crosses the x -axis, and the y -intercept is the point where a line crosses the y -axis. Want a deeper introduction to intercepts? Check out this video. Example: Intercepts from a graph. Looking at the graph, we can find the intercepts. The line crosses the axes at two points:
In analytic geometry, using the common convention that the horizontal axis represents a variable and the vertical axis represents a variable , a -intercept or vertical intercept is a point where the graph of a function or relation intersects the -axis of the coordinate system.
Y-Intercept of a Straight Line. Where a line crosses the y-axis of a graph. Just find the value of y when x equals 0. Example: In the above diagram the line crosses the y axis at y = 1. Example: Here the line crosses the y axis at y = −2. Point. The y-intercept is an (x,y) point with x=0, so we show it like this (try dragging the points):
In an equation in slope-intercept form (y=mx+b) the slope is m and the y-intercept is b. We can also rewrite certain equations to look more like slope-intercept form. For example, y=x can be rewritten as y=1x+0, so its slope is 1 and its y-intercept is 0.
Practice determining what each of the slope, x-intercept, and y-intercept represent in a given linear relationship.
