(50 points) Suppose the light pattern from a fog light can be modeled by the equation x^2/25 - y^2/9=1. One of the points on the graph of this equation is at (6, 3 sqrt 11/5), and one of the x-intercepts is -5. Which coordinate is not a point on the graph?

Answer:

  • Both points are on the graph

Step-by-step explanation:

Given function

  • x^2/25 - y^2/9 = 1

To find

  • Check if given points are on the graph (6, 3 sqrt 11/5) and (-5, 0)

Solution

Verifying the points are on the line by substituting values of x and y:

1.............................

  • 6^2/25 - (3√11/5)²/9 = 1
  • 36/25 - 11/25 = 1
  • 25/25 = 1
  • 1 = 1
  • Correct

2.............................

  • (-5)^2/25 - 0^2/9 = 1
  • 25/25 - 0 = 1
  • 1- 0 = 1
  • 1 = 1
  • Correct
