Final answer:
The y-intercept is the point where a line crosses the y-axis and is found when x = 0; in this case, it is (0, 0.4). The x-intercept is where the line crosses the x-axis, happening when y = 0, which is (0.3, 0) for this graph.
Step-by-step explanation:
To determine the intercepts of a line, we need to find the points where the line crosses the x-axis and the y-axis. The y-intercept is the point where the line crosses the y-axis, and it occurs when x = 0. Conversely, the x-intercept is the point where the line crosses the x-axis, and it happens when y = 0. Given the description of the graph which intersects the y-axis at (0, 0.4) and the x-axis at (0.3, 0), these points are the y-intercept and x-intercept, respectively.
To state them explicitly:
- y-intercept: (0, 0.4)
- x-intercept: (0.3, 0)
The intercepts are found from the graph, but they can also be obtained from the equation of a line, typically expressed as y = mx + b where b is the y-intercept and m is the slope of the line. In this graph, the y-intercept lets you know where on the y-axis the plot line begins, and the x-intercept indicates where the line crosses the x-axis.
