y-intercept
The y-intercept of a line is the point where the line intersects the y-axis
The y-intercept of a line is the point where the line intersects the y-axis. In terms of coordinates, the y-intercept is the point (0, y), where y is the value at which the line crosses the y-axis.
To find the y-intercept of a line, you can use the equation of the line in slope-intercept form, which is y = mx + b. In this equation, m represents the slope of the line, and b represents the y-intercept.
If you are given the equation of the line, you can easily determine the y-intercept by identifying the value of b. For example, if the equation of the line is y = 2x + 3, the y-intercept is the constant term 3. Therefore, the y-intercept is (0, 3).
Another way to find the y-intercept is by graphing the line. You can plot a few points on the graph and then locate where the line crosses the y-axis. The point of intersection will be the y-intercept.
Understanding the concept of y-intercept is important as it allows you to identify where a line crosses the y-axis and helps in determining the initial value or starting point of a linear equation.
