Understanding the Y-Intercept | Definition, Calculation, and Representation as a Coordinate Point

How to write the y-intercept

To write the y-intercept, you need to know the equation of the line in slope-intercept form, which is y = mx + b

To write the y-intercept, you need to know the equation of the line in slope-intercept form, which is y = mx + b. The y-intercept is denoted as b in the equation.

The y-intercept is the point where the line crosses or intersects the y-axis. It represents the value of y when x is equal to 0. In other words, it tells you the starting value of y when x is 0.

To find the y-intercept, you can look at the equation of the line and locate the value of b. For example, if the equation is y = 2x + 3, the y-intercept is 3 because when x is 0, the equation becomes y = 2(0) + 3 = 3.

To write the y-intercept as a coordinate point, you simply write down the value of the y-coordinate and set the x-coordinate to 0. In the example above, the y-intercept can be written as (0, 3).

In summary, to write the y-intercept, you need to identify the value of b in the slope-intercept equation y = mx + b, and then you can represent it as a coordinate point (0, b).
