Find the x- and y-intercepts of the line y=–5x+1/3

.

1 answer

To find the x- and y-intercepts of the line given by the equation \( y = -5x + \frac{1}{3} \), we can follow these steps:

Y-Intercept

The y-intercept occurs when \( x = 0 \).

  1. Substitute \( x = 0 \) into the equation: \[ y = -5(0) + \frac{1}{3} = \frac{1}{3} \] So, the y-intercept is at the point \( (0, \frac{1}{3}) \).

X-Intercept

The x-intercept occurs when \( y = 0 \).

  1. Set \( y = 0 \) and solve for \( x \): \[ 0 = -5x + \frac{1}{3} \] \[ 5x = \frac{1}{3} \] \[ x = \frac{1}{3 \cdot 5} = \frac{1}{15} \] So, the x-intercept is at the point \( \left( \frac{1}{15}, 0 \right) \).

Summary

  • The y-intercept is \( (0, \frac{1}{3}) \).
  • The x-intercept is \( \left( \frac{1}{15}, 0 \right) \).
