Math Problem Statement

Determine the x-intercept and the y-intercept for the equation x + 5y = -5.

Solution

We are tasked with finding the x-intercept and the y-intercept of the equation x+5y=5x + 5y = -5.

1. To find the x-intercept:

The x-intercept occurs when y=0y = 0.

  • Substitute y=0y = 0 into the equation: x+5(0)=5x + 5(0) = -5 x=5x = -5 Thus, the x-intercept is (5,0)(-5, 0).

2. To find the y-intercept:

The y-intercept occurs when x=0x = 0.

  • Substitute x=0x = 0 into the equation: 0+5y=50 + 5y = -5 5y=55y = -5 y=1y = -1 Thus, the y-intercept is (0,1)(0, -1).

Answer:

  • x-intercept: (5,0)(-5, 0)
  • y-intercept: (0,1)(0, -1)

Based on the provided options, the correct answer is the last choice:

  • x-intercept: (5,0)(-5, 0)
  • y-intercept: (0,1)(0, -1)
