Final answer:
The point where the graphical method cuts the vertical axis is known as the y-intercept, which is where the graph intersects the y-axis. For a linear equation of the form y = mx + b, the y-intercept is b, representing the point (0, b) on the graph.
Step-by-step explanation:
The point where a graphical method cuts the vertical axis refers to the location where the graph of a function or an equation intersects the y-axis. In the context of a two-dimensional Cartesian coordinate system, where the horizontal axis is labeled as the x-axis and the vertical axis as the y-axis, this point represents the y-intercept of the graph. In a linear equation written in the standard form y = mx + b, b indicates the y-intercept and represents the value of y when x is zero. This means that the graph of the equation will cross the y-axis at the point (0, b). When plotting a graph using the vertical axis for dependent variables and the horizontal for independent variables, the point where the graph meets the vertical line with an x-coordinate of zero will provide the value of the dependent variable when the independent variable is zero.
