Graphing linear equations is a fundamental skill in mathematics, and the equation y = 4x is a simple example of a linear equation. To graph this equation, follow these steps:

1. Plot the y-intercept. The y-intercept is the point where the graph crosses the y-axis. For the equation y = 4x, the y-intercept is (0, 0) because when x = 0, y = 0.
2. Find the slope of the line. The slope is a measure of how steep the line is. For the equation y = 4x, the slope is 4. This means that for every 1 unit increase in x, y increases by 4 units.
3. Use the slope and the y-intercept to plot additional points. Starting from the y-intercept, use the slope to plot additional points on the graph. For example, to plot the point (1, 4), start at the y-intercept (0, 0) and move up 4 units (because the slope is 4) and then to the right 1 unit.
4. Connect the points with a line. Once you have plotted a few points, you can connect them with a line to complete the graph.

Graphing linear equations is an important skill because it allows you to visualize the relationship between two variables. For example, the equation y = 4x could be used to represent the relationship between the number of hours worked and the amount of money earned. By graphing the equation, you can see how the amount of money earned increases as the number of hours worked increases.

Graphing tangent functions involves understanding the periodic nature of the tangent function. The tangent function is defined as the ratio of the sine of an angle to the cosine of the angle, and its graph exhibits a characteristic wave-like pattern that repeats itself over regular intervals. To accurately graph tangent functions, it is important to identify the key features of the graph, including the period, amplitude, phase shift, and vertical shift.

Tangent functions play a significant role in various fields, including trigonometry, calculus, and engineering. They are used to model periodic phenomena, such as the motion of a pendulum or the variation of temperature over time. Understanding how to graph tangent functions is essential for analyzing and interpreting these types of patterns.
