Math Problem Statement

What is the slope and y intercept for the linear function f(x) = 1/3x

– 5.

Solution

For the linear function f(x)=13x5f(x) = \frac{1}{3}x - 5, the slope and y-intercept can be determined directly from the equation.

The general form of a linear equation is f(x)=mx+bf(x) = mx + b, where:

  • mm is the slope.
  • bb is the y-intercept.

In your function f(x)=13x5f(x) = \frac{1}{3}x - 5:

  • The slope mm is 13\frac{1}{3}.
  • The y-intercept bb is 5-5.

Summary:

  • Slope: 13\frac{1}{3}
  • Y-intercept: 5-5
