Question

Which coordinate is not a point on the graph?

Answer 1

Answer: Option b.

Step-by-step explanation:

To solve this problem you can substitute the points shown in the options into the equation, if the point is on the graph the result must be 1:

a. $\frac{(-6)^{2}}{25}-\frac{(\frac{3\sqrt{11}}{5})^{2}}{9}=1$ (It is on the graph).

b.$\frac{(6)^{2}}{25}-\frac{(\frac{5}{3\sqrt{11}}^{2})}{9}=1.41$ (It is not on the graph).

c. $\frac{(-6)^{2}}{25}-\frac{(-\frac{3\sqrt{11}}{5})^{2}}{9}=1$ (It is on the graph).

d.  $\frac{(-6)^{2}}{25}-\frac{(\frac{-3\sqrt{11}}{5})^{2}}{9}=1$ (It is on the graph).

The answer is the option b.
