How to do you graph #y=4x# by plotting points?
Plug in values for x, solve for y, then pair the corresponding values to find points on the graph.
Plug in values for x, such as 2, 1, 0, 1, 2. The corresponding yvalues would be 8, 4, 0, 4, 8, respectively. Pairing these values together would give you the following coordinates: (2, 8), (1, 4), (0, 0), (1, 4), (2, 8). Connect these points (preferably using a ruler), and you will obtain the graph of the function in question.

To graph the equation (y = 4x) by plotting points, follow these steps:

Choose Values for (x): Select at least two values for (x). It's often helpful to include zero, a positive, and a negative number to get a clear idea of the line's direction. For example, let's use (x = 1), (x = 0), and (x = 1).

Calculate Corresponding (y) Values: Use the equation (y = 4x) to find the corresponding (y) values for each chosen (x) value.
 For (x = 1), (y = 4(1) = 4).
 For (x = 0), (y = 4(0) = 0).
 For (x = 1), (y = 4(1) = 4).

Plot the Points: Plot the points on a graph. The points from our example are ((1, 4)), ((0, 0)), and ((1, 4)).

Draw the Line: Connect the points with a straight line. Since (y = 4x) is a linear equation, the points should line up perfectly, and your line will extend infinitely in both directions.
By following these steps, you'll have accurately graphed the equation (y = 4x).

When evaluating a onesided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
