When dealing with equations, it's essential to understand the relationship between points on the graph and the values that make the equation true. In this article, we'll explore the concept of points on the graph of an equation and determine which statement must be true if the point ${$ (1,4)$}$ is on the graph.

What Does it Mean for a Point to be on the Graph of an Equation?

A point ${$ (x,y)$}$ is said to be on the graph of an equation if the values of ${$ x$}$ and ${$ y$}$ satisfy the equation. In other words, when we substitute the values of ${$ x$}$ and ${$ y$}$ into the equation, the equation holds true.

Analyzing Statement A

Statement A claims that the values ${$ x=1$}$ and ${$ y=4$}$ make the equation true. This statement is true if the point ${$ (1,4)$}$ is on the graph of the equation. When we substitute ${$ x=1$}$ and ${$ y=4$}$ into the equation, the equation should hold true.

Analyzing Statement B

Statement B claims that the values ${$ x=1$}$ and ${$ y=4$}$ are the only values that make the equation true. This statement is not necessarily true. There may be other values of ${$ x$}$ and ${$ y$}$ that satisfy the equation, in addition to ${$ x=1$}$ and ${$ y=4$}$.

Why Statement A is the Correct Answer

The correct answer is Statement A. If the point ${$ (1,4)$}$ is on the graph of an equation, then the values ${$ x=1$}$ and ${$ y=4$}$ must make the equation true. This is because the point ${$ (1,4)$}$ is defined as the values ${$ x=1$}$ and ${$ y=4$}$ that satisfy the equation.

Example: Understanding the Relationship Between Points and Equations

Let's consider an example to illustrate the concept. Suppose we have the equation ${$ x^2 + y^2 = 25$}$. If the point ${$ (3,4)$}$ is on the graph of this equation, then the values ${$ x=3$}$ and ${$ y=4$}$ must make the equation true.

Substituting ${$ x=3$}$ and ${$ y=4$}$ into the equation, we get:

${$ (3)^2 + (4)^2 = 25$ [$9 + 16 = 25$ [$25 = 25$

As we can see, the equation holds true when we substitute [ $x=3\$}$ and ${$ y=4$}$ into the equation. Therefore, the point ${$ (3,4)$}$ is on the graph of the equation.

Conclusion

In conclusion, if the point ${$ (1,4)$}$ is on the graph of an equation, then the values ${$ x=1$}$ and ${$ y=4$}$ must make the equation true. This is because the point ${$ (1,4)$}$ is defined as the values ${$ x=1$}$ and ${$ y=4$}$ that satisfy the equation.

Q: What is the relationship between a point on the graph and the equation?

A: A point ${$ (x,y)$}$ is said to be on the graph of an equation if the values of ${$ x$}$ and ${$ y$}$ satisfy the equation. In other words, when we substitute the values of ${$ x$}$ and ${$ y$}$ into the equation, the equation holds true.

Q: Can a point be on the graph of an equation if the values of ${$ x$}$ and ${$ y$}$ do not satisfy the equation?

A: No, a point cannot be on the graph of an equation if the values of ${$ x$}$ and ${$ y$}$ do not satisfy the equation. By definition, a point on the graph of an equation must satisfy the equation.

Q: What is the difference between a point on the graph and a point that is not on the graph?

A: A point on the graph of an equation satisfies the equation, while a point that is not on the graph does not satisfy the equation. In other words, a point on the graph is a solution to the equation, while a point that is not on the graph is not a solution.

Q: Can a point be on the graph of an equation if the equation is not true?

A: No, a point cannot be on the graph of an equation if the equation is not true. By definition, a point on the graph of an equation must satisfy the equation, and if the equation is not true, then the point cannot be on the graph.
