📖 1 of 2

The Y-intercept is the point where a line crosses the Y-axis on a graph. This means it is the value of Y when X is zero. To find the Y-intercept in an equation, you can set X to zero and solve for Y. For example, in the equation y = 2x + 3, if you substitute 0 for x, it becomes y = 2(0) + 3. This simplifies to y = 3, so the Y-intercept is 3. On a graph, this point would be located at (0, 3).

The Y-intercept helps us understand the starting point of a line and can be useful in real-life situations, like predicting costs or analyzing trends. Knowing the Y-intercept allows us to make sense of how two variables relate to each other, particularly in linear equations.
