What Is y=x?

y=x is an equation commonly used in mathematics. It is an algebraic equation that expresses a linear relationship between two variables, x and y. This equation is often used to determine the slope of a line when graphed on a coordinate plane.

How Does y=x Work?

The equation y=x is a linear equation. This means that when graphed on a coordinate plane, it will form a straight line. The slope of this line is 1, meaning that for every unit increase in x, y will increase by the same amount. For example, if x increases by one, y would increase by one. This equation is useful for determining the slope of a line.

Examples of y=x

Here are some examples of y=x equations and how they can be used:

y=x+2 - This equation shows that for every unit increase in x, y will increase by two.
y=x-4 - This equation shows that for every unit decrease in x, y will decrease by four.
y=2x - This equation shows that for every unit increase in x, y will increase by two.

Solving y=x

Solving y=x is a relatively simple task. To solve for x, simply rearrange the equation so that x is on the left side of the equation and y is on the right. For example, if the equation is y=x+2, then you can rearrange it to read x=y-2. To solve for y, simply rearrange the equation so that y is on the left side of the equation and x is on the right. For example, if the equation is y=2x, then you can rearrange it to read y=2x.

Applications of y=x

y=x can be used in a variety of applications, including:

Calculating the slope of a line
Graphing linear equations
Analyzing linear relationships between two variables
Solving linear equations

Contoh Soal y=x

Here is an example of a y=x problem:

If y=x+3, what is the value of x when y=7?

To solve this problem, simply rearrange the equation to read x=y-3. Since y=7, x=7-3=4.

Conclusion

y=x is a simple equation that expresses a linear relationship between two variables. It can be used to calculate the slope of a line, graph linear equations, analyze linear relationships between two variables, and solve linear equations. With the help of a few simple examples, you should now have a better understanding of how y=x works.
