Math Problem Statement

Determine the intercepts of the line shown in the graph.

Solution

To determine the intercepts of the line shown in the graph:

1. Finding the y-intercept:

The y-intercept occurs where the line crosses the y-axis. At this point, the x-coordinate is always 00.

  • From the graph, the line crosses the yy-axis at y=4y = 4.
  • Therefore, the yy-intercept is (0,4)(0, 4).

2. Finding the x-intercept:

The x-intercept occurs where the line crosses the x-axis. At this point, the y-coordinate is always 00.

  • From the graph, the line crosses the xx-axis at x=8x = -8.
  • Therefore, the xx-intercept is (8,0)(-8, 0).

Final Answer:

  • yy-intercept: (0,4)(0, 4)
  • xx-intercept: (8,0)(-8, 0)
