Question

Which coordinate is not a point on the graph?

Answer 1

Answer: Option b.

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.
`((-6)^(2))/(25)-(((3√(11))/(5))^(2))/(9)=1` (It is on the graph).

b.
`((6)^(2))/(25)-(((5)/(3√(11))^(2)))/(9)=1.41` (It is not on the graph).

c.
`((-6)^(2))/(25)-((-(3√(11))/(5))^(2))/(9)=1` (It is on the graph).

d.
`((-6)^(2))/(25)-(((-3√(11))/(5))^(2))/(9)=1` (It is on the graph).

The answer is the option b.
