Y-intercept
The y-intercept is a term used in mathematics to describe the point where a line or a curve intersects the y-axis on a coordinate plane
The y-intercept is a term used in mathematics to describe the point where a line or a curve intersects the y-axis on a coordinate plane. In other words, it is the value of the dependent variable (usually represented as “y”) when the independent variable (usually represented as “x”) is equal to zero.
To find the y-intercept of a linear equation, you can set the value of x to zero and solve for y. For example, consider the equation of a line: y = mx + b. Here, m represents the slope of the line, and b represents the y-intercept. By setting x = 0 in the equation, you can find the value of y when x is zero, which gives you the y-intercept.
For instance, if the equation of a line is y = 2x + 3, then the y-intercept is the point (0, 3), where the line crosses the y-axis. The y-coordinate in this case is 3.
In general, the y-intercept plays an essential role in graphing linear equations and helps determine the starting point of the line on the y-axis.
