Math Problem Statement

Find the x-intercept of f(x) = (1/5)x - 6. Enter your answer as a point, (a, b).

Solution

To find the xx-intercept of the function f(x)=15x6f(x) = \frac{1}{5}x - 6, we set f(x)=0f(x) = 0, because the xx-intercept occurs where the function crosses the xx-axis, and at that point, y=0y = 0.

Steps:

  1. Set f(x)=0f(x) = 0: 0=15x60 = \frac{1}{5}x - 6

  2. Solve for xx: 15x=6\frac{1}{5}x = 6 Multiply both sides by 5: x=30x = 30

  3. The xx-intercept is (30,0)(30, 0).

Final Answer:

The xx-intercept is: (30,0)(30, 0)

  2. What is the slope of the line f(x)=15x6f(x) = \frac{1}{5}x - 6?
  3. How would the graph of f(x)=15x6f(x) = \frac{1}{5}x - 6 change if the slope were negative?
  4. How do you verify if a point lies on the line f(x)=15x6f(x) = \frac{1}{5}x - 6?
  5. What is the geometric significance of the xx-intercept in a real-world context?

Tip: When solving for intercepts, remember that the xx-intercept occurs when y=0y = 0, and the yy-intercept occurs when x=0x = 0.
