Final answer:
The y-intercept of the line is 25.
Step-by-step explanation:
The y-intercept of a line represents the point where the line crosses the y-axis. To find the y-intercept, we can use any of the given points that lie on the line, because all points on the same line have the same y-intercept. Let's take the first point (-72, 25) as an example. The x-coordinate of this point is -72, so the line passes through the y-axis at x = 0. Now we can find the corresponding y-coordinate, which is 25. Therefore, the y-intercept of the line is 25.
