Final answer:
The y-intercept in the given options is A) Y-axis (0, 13.0), indicating the point where the line crosses the y-axis at y-value 13.0.
Step-by-step explanation:
The y-intercept of a line is the point where it crosses the y-axis. In the given information, option A) Y-axis (0, 13.0) represents the y-intercept since the x-value is 0. This means that when x is zero, the value of y is 13.0, which is where the line would cross the y-axis on a graph. Understanding the y-intercept is vital for graphing equations, as it provides a starting point for drawing the line. The formula for a straight line is y = mx + b, where 'b' represents the y-intercept and 'm' represents the slope.
